Why don't you ask your pastor about James 1:12 and ask him to explain to you how you can overcome that "pre existing condition" which "automatically responds by committing adultery". Listen to your pastor as he explains that we have the ability to endure the temptation without falling into sin, in which case James 1:12 tells us Blessed is the man that endureth temptation: for when he is tried, he shall receive the crown of life, which the Lord hath promised to them that love him.
James 1:12 is just as much a part of the Bible as whatever verse you're relying on to claim "we are all murderers and adulterers". And you're certainly not listening to me as I try to help you overcome your "pre existing condition" which "automatically responds by committing adultery"
As for myself, I'll continue to rely on God to perfect, establish, strengthen, settle me as I endure the sufferings of this present evil world.
