Sin has separated us from God’s presence, but it cannot separate us from God’s love. Our sin is not a barrier to salvation. Sin is not an impediment to salvation, it is the reason we need salvation.
Dealing with sin was the cause that brought Jesus to a little town called Sychar to meet with the "woman at the well" (John 4:1-42) Dealing with sin was the cause that brought Jesus from heaven to earth.
The cause (sin) cannot be an impediment to the effect (salvation).
