Through Christ we are saved. He tells us to repent, we do so. He tells us to be baptized, we do so. If you have faith in Him, you will do what He says and not argue it, or make excuses of why not. You try to put it off, or say its insignificant, even tho the Bible says otherwise, and fall to the very temptation Satan has laid before you. He doesnt want anyone to be saved, he knows his doom is certain, and he'll do whatever he can, including attempts to pervert God's Word, to keep people from being saved.
In reference to the works, again, you do nothing at baptism aside from make a choice. It is something done to you. When you accept Christ, its a choice, when you repent, its a choice. Trying to discredit something as a mere work yet support other things that are just as much a choice and no more is thoughtless, only attempts to make excuses. Just something to think about, anyways.
