Hypothetical situation: Joe, aged 17, responds to the Pastor's sermon on Sunday, and feels he should give his life to Christ. He is baptized the next Sunday. Over the next few months, he begins to 'backslide', and eventually drops-out. He lives the life of a heathen and grievous sinner for the next 15 years. One night, he happens to attend a 'Crusade' in his town, and this night, he is greatly convicted of his sin. This time, with all sincerity, He asks Jesus to forgive Him, He asks Jesus to come in to his heart, and he pledges to really live for Jesus. Question: Does Joe need to be baptized again? (The first time he was baptized, was his faith 'sincere'? If it wasn't 'sincere' was it really a baptism?)
