Yes, it is possibly the deepest question, after the proposition that we are saved by faith not by works, lest any man boast of earned merit. The Jailer asked ‘What must I do to be saved?’ What did Paul answer? It is that simple, yet so hard for some to let God be God in them.
Pax vobiscum
By Grace are we saved through Faithe in Jesus, not of works lest any man boast. That is the Way to be born from Above.
