I asked the question of if he trusted that Jesus took his sins 100%, but committed a sin, then died, would he go to heaven? He said he would go to hell because he never repented for that sin. No amount of trying to convince Dylan that Christ made a one-time payment for all of his sins was enough to satisfy him. He was making a work out of repentance, making it a pre-requisite for salvation every time he sinned.
So how can we protect ourselves and others from the sin of pride and over-confidence? Well, we humble ourselves to God alone. We ask for His protection. We submit to His will, praying “Let not the foot of pride come against me, and let not the hand of the wicked drive me away.”. Pride is always at the root of all sin, and it takes a humble heart for God to tear it out. If we trust in ourselves, then sooner or later we will be destroyed.
Then he brought up James regarding faith plus works. Then I knew he was lost. He was going to twist the scripture to mean we need faith plus works to be saved. But this is a false application. In context, it is saying that works is a result of faith, not a pre-requisite for it. I told him as such, to read the whole book of James instead of cherry-picking the verses you want, so that you can invent your own doctrine.
