1 John 4:13 (BSB):
"By this we know that we remain in Him, and He in us: He has given us of His Spirit."
This verse answers one of the most important questions a person can ask: How can I know that I truly belong to God?
John points directly to the Holy Spirit. Assurance is not grounded in emotions, religious activity, or outward appearances—it is grounded in the presence and work of the Spirit within you. God gives His Spirit to every true believer, and His indwelling is the evidence that you are united to Christ.
The Spirit actively produces fruit. He leads you into truth, convicts you of sin, and grows in you a love for God and for others (Galatians 5:22–23). If the Spirit dwells in you, your life will not remain unchanged.
This also means assurance is both a comfort and a test. Comfort—because your salvation is rooted in God’s work, not yours. Test—because if there is no evidence of the Spirit’s transforming power, there is no biblical basis for assurance.
So examine your life honestly. Do you see the Spirit’s work? Do you hate your sin? Do you love Christ? Do you desire to obey God’s Word?
If so, take confidence—not in yourself, but in God, who has given you His Spirit as the guarantee that you dwell in Him, and He in you.
That's it for this podcast. Remember, Jesus loves you and is just a prayer away.
