I was watching Joseph Prince again today and something he said really encouraged me in God's Grace (Jesus).
It was really short but made me slap my head and say "duh!" ;)
He made the point that sinners, born in Adam, can do nothing "good" in order to bring them out of their sin in Adam. Sinners can't do anything good enough to make them right with God.
And so in the same way, people born in Second Adam (Jesus) cannot do anything bad in order to bring them out of their righteousness in Christ. There is nothing that they can do that will make them sinners, just like there nothing a sinner can do can make themselves righteous.
That, my friend, is why exactly why there is Eternal Security for us who trust in Jesus Christ, the Son of God. Jesus has put away sin forever by the sacrifice of Himself! There is no other sacrifice to be made, so if He didn't do it all, then you, my friend are screwed because Scripture does not say, "without confession there is no forgiveness of sins." It also does not say, "without repentance there is no forgiveness of sins." The scripture says: "Without the shedding of Blood, there is no forgiveness of sins."
You either accept this or you reject it.
