I Can Do!

Philippians 2:13 For it is God which worketh in you both to will and to do of his good pleasure.

Compared to:

Philippians 4:13 I can do all things through Christ which strengtheneth me.

Through Christ/God we are energized to BOTH will and do the will of God.

2 Corinthians 8:11 Now therefore perform the doing of it; that as there was a readiness to will, so there may be a performance also out of that which ye have.
