Guidance From a Mature Believer: Ethics of the Last Hour
GUIDANCE FROM A MATURE BELIEVER · 1 JOHN 2:18–29
Finish the Shift Well
The Ethics of the Last Hour
“Let the word of Christ dwell richly among you, in all wisdom teaching and admonishing one another through psalms, hymns, and spiritual songs, singing to God with gratitude in your hearts. And whatever you do, in word or in deed, do everything in the name of the Lord Jesus, giving thanks to God the Father through him.”
— Colossians 3:16–17 (CSB)
Picture the last hour of a twelve-hour night shift. The coffee went cold somewhere around three in the morning. Your feet ache, your eyes burn, and the clock at the end of the hall seems to have stopped moving altogether.
This is the hour when shortcuts start whispering. Chart it later. Skip that last round. Nobody will notice.
Somebody will. The oncoming shift is already pulling into the parking lot, and whatever you leave behind is exactly what they will find when they walk through the door.
Friend, the apostle John says we are living in that hour.
A Grandfather’s Warning
By the time John wrote this letter, he was an old man. He had walked the roads of Galilee with Jesus, leaned against Him at the Last Supper, stood at the foot of the cross, and outlived nearly every other apostle. So when he writes, “Children, it is the last hour,” hear the calm, steady voice of a grandfather who has seen enough to know what matters and what does not.
This week in our series, Guidance From a Mature Believer, we sit at John’s feet in 1 John 2:18–29 and ask a very practical question. If we are living in the last hour, how should we live? Call it the ethics of the last hour.
The Hour We Are Living In
“Children, it is the last hour. And as you have heard that antichrist is coming, even now many antichrists have come. By this we know that it is the last hour.”
— 1 John 2:18 (CSB)
When John says “last hour,” he means the whole stretch of time between Jesus’ ascension and His return. The church has lived in that hour for nearly two thousand years, and we are closer to its end today than John was. Scripture tells us that just before the world ends, one great antichrist will arise (Revelation 13; 19:20; 20:10). Long before that final figure appears, though, John wants us to know that many smaller antichrists are already at work.
Who are they? John describes people who once sat in the same gatherings and sang the same songs: “They went out from us, but they did not belong to us” (v. 19). They were false teachers who pretended to be Christians and worked to lure weaker members away from Christ. Their leaving simply revealed what had been true all along.
How to Spot a Counterfeit
Bank tellers learn to spot counterfeit bills by handling the real thing day after day. John gives us the same kind of training. An antichrist is anyone who denies the authority and sovereignty of Jesus.
“Who is the liar, if not the one who denies that Jesus is the Christ? This one is the antichrist: the one who denies the Father and the Son. No one who denies the Son has the Father; he who confesses the Son has the Father as well.”
— 1 John 2:22–23 (CSB)
Counterfeits rarely announce themselves. They usually sound warm, reasonable, and even spiritual. Here are a few warning signs worth watching for:
A smaller Jesus. He is praised as a good teacher or a fine example, yet never bowed to as Lord.
A Father without the Son. The message talks about God in general terms but sets Jesus aside as optional.
A pull away from the fellowship. The teaching slowly isolates you from believers who love you and would speak the truth to you.
A “new” word that overrides the old one. You are asked to trade what Scripture plainly says for a fresh revelation.
You Have an Anointing
Here is the good news I want you to hold tightly: you are well equipped for this hour. When a person becomes a Christian, he or she receives the Holy Spirit, who communicates the truth. John calls this “an anointing from the Holy One” (v. 20).
“As for you, the anointing you received from him remains in you, and you don’t need anyone to teach you. Instead, his anointing teaches you about all things and is true and is not a lie; just as it has taught you, remain in him.”
— 1 John 2:27 (CSB)
Jesus promised this very gift before He went to the cross:
“But the Counselor, the Holy Spirit, whom the Father will send in my name, will teach you all things and remind you of everything I have told you.”
— John 14:26 (CSB)
Because the Holy Spirit lives within us, Christians have an inner Guide who keeps us from going astray. He works hand in hand with the Word He inspired, which is why Paul urges us to let the word of Christ dwell richly among us. To stay true to Christ, we follow both His Word and His Spirit. When we are led by the Spirit, we can stand against every false teacher, and one day against the antichrist himself.
So here is my gentle nudge: ask the Holy Spirit to guide you each day. Before you scroll, before you turn on the news, before you open your email, pray something as simple as, “Holy Spirit, teach me today. Help me discern truth from error.”
Remain
“What you have heard from the beginning is to remain in you. If what you have heard from the beginning remains in you, then you will remain in the Son and in the Father. And this is the promise that he himself made to us: eternal life.”
— 1 John 2:24–25 (CSB)
Count how many times John uses the word remain in this short passage. He keeps circling back to it the way a mother repeats the most important instruction as her child heads out the door.
A person who accepts Christ as God’s Son also accepts God’s way of revealing Himself to the world. The two are one and cannot be separated. Anyone who tries to keep the Father while setting the Son aside ends up with neither. Remaining sounds restful, and it is, yet anyone who has kept a long friendship alive knows it also takes intention. We remain by returning to the Word, to prayer, and to the fellowship of believers again and again.
The Visible Proof
“If you know that he is righteous, you know this as well: Everyone who does what is right has been born of him.”
— 1 John 2:29 (CSB)
The visible proof of being a Christian is right behavior. True faith always results in good deeds. Those who claim to have faith and who consistently do what is right are true believers.
Please hear this carefully, because it matters. Good deeds cannot produce salvation:
“For you are saved by grace through faith, and this is not from yourselves; it is God’s gift—not from works, so that no one can boast.”
— Ephesians 2:8–9 (CSB)
Yet good deeds are the necessary proof that true faith is actually present:
“In the same way faith, if it doesn’t have works, is dead by itself.”
— James 2:17 (CSB)
Paul and James are holding the same coin from two sides. A healthy apple tree never strains to produce apples. Fruit is simply what life looks like when it is growing.
Peter’s Blueprint for the Last Hour
The apostle Peter, writing to believers under pressure, gave a practical list that fits John’s warning like a glove:
“The end of all things is near; therefore, be alert and sober-minded for prayer. Above all, maintain constant love for one another, since love covers a multitude of sins. Be hospitable to one another without complaining. Just as each one has received a gift, use it to serve others, as good stewards of the varied grace of God.”
— 1 Peter 4:7–10 (CSB)
Here is what the ethics of the last hour look like in everyday clothes:
Do not be distracted by the world. Stay alert and clear-headed. Many good things can quietly crowd out prayer.
Love one another. Keep your love at full strength, especially toward the people who are hardest to love.
Care for one another. Open your door and your table, and do it without grumbling.
Find joy in serving others. Service offered with a glad heart becomes worship.
Steward and serve God’s indwelling Spirit. The gifts He has placed in you are on loan for the good of others.
Glorify Jesus in everything. The goal of every word and every act of service is that God be glorified through Jesus Christ.
Jesus Is Our Hero
A Christian is someone who submits to the lordship and identity of Jesus. That surrender shapes how we talk, how we spend, how we forgive, and how we treat the person in front of us.
Have you ever watched a child imitate a hero? The walk, the voice, the cape tied around the neck with a dish towel. Children copy the ones they admire most. Imitate Jesus, because He is our Hero! Live your faith every day and everywhere: at the bedside, in the checkout line, at the family table. Whatever you do, in word or in deed, do everything in the name of the Lord Jesus.
What God Has Told Us Is Coming
Scripture does not leave us guessing about how this story ends. God has told us three things plainly:
Opposition to God and His own will only grow. We should not be surprised when faith is mocked or truth is twisted. John warned us it would be so.
Those who oppose God will face eternal condemnation (Revelation 20:11–15). This truth should break our hearts and send us to our knees for the people we love who are still far from Him.
God’s people will have eternal life and will be eternally satisfied (John 4:14; Revelation 22:12–17). Every thirst we carry will finally be quenched.
“But whoever drinks from the water that I will give him will never get thirsty again. In fact, the water I will give him will become a well of water springing up in him for eternal life.”
— John 4:14 (CSB)
“Both the Spirit and the bride say, “Come!” Let anyone who hears, say, “Come!” Let the one who is thirsty come. Let the one who desires take the water of life freely.”
— Revelation 22:17 (CSB)
Confidence When He Appears
“So now, little children, remain in him so that when he appears we may have confidence and not be ashamed before him at his coming.”
— 1 John 2:28 (CSB)
Let’s go back to that night shift for a moment. The nurse who finishes well can hand off her patients with her head up. She can look the oncoming nurse in the eye and say, “Everything is in order.” That is the confidence John wants for you and for me when Jesus appears.
We will not get there by straining harder in our own strength. We get there by remaining: staying close to the Word, listening to the Spirit, loving and serving the people God has placed around us, and keeping our eyes on our Hero.
So, let me leave you with the question this message leaves with all of us: How will you live while waiting for Jesus to return?
Your Plan of Action
Choose one item from each column, or work straight across a row. Small, faithful steps are how we finish the shift well.
Daily | This Week | This Month | Ongoing |
Pray for guidance. Before your phone or the news, ask, “Holy Spirit, guide me today and help me tell truth from error” (1 John 2:27). | Read 1 John 2:18–29 three times, slowly. Circle every “remain.” Ask what it looks like to remain in Him this week. | Memorize Colossians 3:16–17. Let the word of Christ dwell richly enough to come back to you when you need it. | Test every voice. Measure sermons, posts, podcasts, and “new revelations” against what Scripture says about Jesus. |
Do one quiet act of care that no one will thank you for. Let love, not applause, be the reason. | Practice hospitality without complaining (1 Peter 4:9). Share a meal, a porch visit, or a phone call with someone who is lonely. | Name your gift. Ask a trusted believer what gift they see in you, then find one place to use it serving others. | Stay close to the fellowship. Notice who is drifting, and reach out before they are gone. |
Close the day honestly. Ask, “If Jesus had appeared today, would I be glad for Him to find me as I am?” | Unplug from one distraction that crowds out prayer (1 Peter 4:7). Give that time back to God. | Pray by name for three people who do not yet know Christ. Ask God for an open door to share your hope. | Imitate your Hero. Live your faith every day and everywhere, doing everything in the name of the Lord Jesus. |
Help · Hope · Home You were never meant to keep watch through the last hour alone. If false voices have shaken you, if your faith feels tired, or if you have never settled the question of who Jesus is, reach out. Let someone pray with you and walk with you. There is help for today, hope for tomorrow, and a home waiting at the end of the shift. |
