Your comment concerning imputed versus infused grace is straight on, as well. The same grace God is believed by Catholics to have given Mary to purify her soul in preparation to receive the embryonic Savior, is given to ALL those who come to Him in faith, receiving the gift of eternal life which is ours because of that same grace of God and we also are indwelled - until redemption - with the Holy Spirit. We are saved because God has imputed the righteousness of Christ to our "account" and we are found IN Christ, not having our own righteousness, but that which is through the faith of Christ, the righteousness of God by faith (Philippians 3:9). The entire dynamic changes, doesn't it? It's not what we do for God, but what He has done for us. Praise His wonderful name!
I'm signing off. I hope you have a wonderful week.
We have to leave behind the rationalizations, the justifications, the excuses, and get it all out on the table,...
The spirit can be our guide in this (possibly even mUST be?).
