How do you know that you belong to Jesus? What does it mean to have the assurance that you are living your lives for Him? Assurance comes from the Holy Spirit who lives in the believer, but how do you know you have it? Whoever is willing to confess Christ before the world is the one who is assured of their faith in Him. Assurance breeds confidence and strength in your life. From that, you will never fear or worry about the day of judgment. An exposition of 1 John 4:13-21.
