I can do all things through Christ which strengtheneth me.

The joy of the LORD is your strength.

But we have this treasure in earthen vessels, that the excellency of the power may be of God, and not of us.

Not by might, nor by power, but by my spirit, saith the LORD of hosts.

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. For when I am weak, then am I strong.

In quietness and in confidence shall be your strength.

But 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.

As thy days, so shall thy strength be.
