The wonderful thing about obeying the gospel is the fresh start that it gives the candidate. Our sins are completely wiped cleaned and cannot be brought back ever again. Heb 10.17.
The man baptized by Philip knew this because after his conversion he went about his way, celebrating his new condition. Acts 8.39 And with all the past deeds being erased, it is

But it is horrible for one to commit sins in his twenties and quit doing so; only to have to answer for them at the judgement bar. But that is what will happen, if a person doesn’t obey the gospel, thereby having those sins washed away. Act 22.16
The best thing anyone can do and may I say the only thing one can do, is obey the gospel.
