To imagine that they were "turning from" only unbelief...without conscience of their prior murder, theft, adultery, blasphemy, covetousness, is ludicrous. Were they to "repent" of those things at some other time? If they don't believe in Him, they won't get baptized...into Him and into His death, burial, and resurrection. (Rom 6:3-6) They won't crucify the flesh, with the affections and lusts, without baptism. (Gal 5:24) They won't be able to "cease from sin". (1 Peter 4:1) Your inability to see the seriousness of every sin worries me. As the repentant don't commit further sin after conversion, any "defilement" is being done by unbelieving posers. They don't have the Spirit of God, but the spirit of the "prince of the power of the air, the spirit that now worketh in the children of disobedience:" (Eph 2:2) You are confusing "death" with the "second death". Don't confuse "life" with the condition of the skin. You are in error. EVERY believer will be "found in Him". Only unbelievers offend God.. Doubt is the antithesis of belief. Pick which "team" you are on! Isn't it interesting that even the unfaithful would call upon the Lord for help, before His resurrection and glorification? I thank God for the gift of the Holy Ghost, given for a true "turn from" sin!
