Colossians

I can do all things through Christ which strengtheneth me.

Finally, my brethren, be strong in the Lord, and in the power of his might.

That he would grant you, according to the riches of his glory, to be strengthened with might by his Spirit in the inner man;

And 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.

He giveth power to the faint; and to them that have no might he increaseth strength.
