The point you and others keep missing?Did Paul deserve the power, and the grace that God told him was sufficient for him?
The meaning is getting twisted.
Grace is God's power that makes us able to become what is deserving of God's favor!
I am what I am by the grace of God.
1 Corinthians 15:10
It is what grace makes us to become that will be what merits God's favor!
Grace in itself is not unmerited favor.
Grace is God's means to place us in a position, so He can show us His favor!
First, grace must develop in us a new capacity for His favor and blessings!
If we keep walking in grace and finding more and more truth?
The blessings will come.
God will not pour into a cup that which it can not hold and contain His favor.
A cup able to contain what it is He wishes to give us.
If we continue growing more and more in grace and truth?
God then pours more, and eventually our cup runs over!
God wants our cup to become what merits His favor!
Grace is the only means to make our cup able to merit what we naturally could not merit.
Big difference!
