Remember, in order to be saved and enjoy all God’s blessings (not the least of which is salvation), a person must have faith (Jn. 8:24), be willing to repent (Lk. 13:3), and after confessing Christ as Lord, the final step is water baptism (Rom. 6:3; 1 Cor. 12:13; 1 Pet. 3:20-21). Bible baptism is by immersion only (“burial,” Rom. 6:4), and once it is done, heaven puts that person “into Christ” (Gal. 3:27; Rom. 6:3). After proper baptism a person has their sins forgiven (Acts 2:38).
