Dear silly man! You can't earn grace.
Romans 3:23
for all have sinned and fall short of the glory of God,
Romans 10:9
If you declare with your mouth, Jesus is Lord, and believe in your heart that God raised him from the dead, you will be saved.
Ephesians 2:8-9
For it is by grace you have been saved, through faithand this is not from yourselves, it is the gift of God not by works, so that no one can boast.
That's the long & short of it.
yep ... full agreement.
