The only grounds of acceptance before God is the death of Christ alone imputed to the elect alone

When the Bible says in 1 John 3 that believers in Christ does not commit sin it does not at all say that believers do not continue to sin either by habit or accident. But what it is saying is simple the Bible tells us how to please God. It also tells us that no one has pleased God and that God will one day judge the nations on account of their sins. Now it also tells us the only ground of acceptance before God which is in Christ alone. For after the sin of the first parents who were our representatives all of us also fell in them. Because of this the law demanded our death for lack of perfect obedience. No one is righteous but that one that gave his life on the cross for the sins of the elect alone. It is this death that is now imputed to the elect so that in Him they live.
