Will there ever come a time in eternity where we will be able to stand in the presence of God by our own righteousness?
Christ Blood will cover all of our short comings. With out Christ no one stands but through Christ and Jesus being by your side, we will stand before the Father and His blood will keep us safe and in Right Standing.
Didn't Adam do that?
Yup, a useless bunch because we were never created to live apart from God. Dead people are pretty useless, and that is exactly what we are without God living inside of us...dead to everything pertaining to God.MmmmmNO
Not possible by our own powers.
Face it, we are a useless bunch on our own.
