Be of good courage, and he shall strengthen your heart, all ye that hope in the Lord.
If thou faint in the day of adversity, thy strength is small.
Hast thou not known? hast thou not heard, that the everlasting God, the Lord, the Creator of the ends of the earth, fainteth not, neither is weary? there is no searching of his understanding.
He giveth power to the faint; and to them that have no might he increaseth strength.
Even the youths shall faint and be weary, and the young men shall utterly fall:
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.
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.
Therefore 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.
I can do all things through Christ which strengtheneth me.
