Be strong in the Lord, and in the power of his might.

My brethren, be strong in the Lord, and in the power of his might. Eph. 6:10

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. II Cor. 12:9, 10

I will go in the strength of the Lord GOD: I will make mention of thy righteousness, even of thine only. Psa. 71:16

I can do all things through Christ which strengtheneth me. Phil. 4:13

I also labour, striving according to his working, which worketh in me mightily. Col. 1:29

We have this treasure in earthen vessels, that the excellency of the power may be of God, and not of us. II Cor. 4:7

The joy of the LORD is your strength. Neh. 8:10

Strengthened with all might, according to his glorious power, unto all patience and longsuffering with joyfulness. Col. 1:11
