While the entire Bible stresses certainty and assurance, there’s one section of Scripture that stakes out this theme as its central focus—the letter of 1 John.
As we carefully read through 1 John, we notice a five-fold argument for the assurance of salvation—five of the birthmarks of the Christian.
The Birthmark of Confession
The first is the birthmark of confession, described in 1 John 5:1: “Whoever believes that Jesus is the Christ is born of God.” Before you can have assurance of salvation, you have to believe and be saved. You have to confess Jesus Christ as Lord. Some people assume they are saved because they grew up in a Christian culture, or they have gone to church all their lives, or they have been baptized, or they have tried to live a good life. Yet they’ve never distinctly and personally confessed Jesus Christ as their Savior and Lord.
The Bible teaches that we are sinners, separated from God by a sinful nature. We can never earn, buy, or climb our way into heaven. By our own efforts or goodness, we can never be saved. That’s why God became a man who lived a wholly righteous life, died on the cross, shed His blood for us, and rose from the dead. He paid our penalty, took our judgment upon Himself, and He offers us the opportunity to be born again.
