Isaiah 40:29–31 (KJV) — “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.”
2 Corinthians 12:9 (KJV) — “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.”
Psalm 73:26 (KJV) — “My flesh and my heart faileth: but God is the strength of my heart, and my portion for ever.”
