Philippians 4:11

I can do all things through Christ which strengtheneth me.

⁹And he said unto me, My grace is sufficient for thee: for my strength is made perfect in weakness. Most gladly therefore will I rather glory in my infirmities, that the power of Christ may rest upon me. ¹⁰Therefore I take pleasure in infirmities, in reproaches, in necessities, in persecutions, in distresses for Christ's sake: for when I am weak, then am I strong.

²⁹He giveth power to the faint; and to them that have no might he increaseth strength. ³⁰Even the youths shall faint and be weary, and the young men shall utterly fall: ³¹But they that wait upon the Lord shall renew their strength; they shall mount up with wings as eagles; they shall run, and not be weary; and they shall walk, and not faint.

I am the vine, ye are the branches: He that abideth in me, and I in him, the same bringeth forth much fruit: for without me ye can do nothing.

It is God that girdeth me with strength, and maketh my way perfect.
