Have I not commanded you? Be strong and of good courage; do not be afraid, nor be dismayed., For the Lord your God is with you wherever you go. Joshua 1:9
Wait on the Lord; be a good courage and He shall strengthen your heart; wait, I say, on the Lord! Psalm 27:14
God is our refuge and strength, very present help in trouble. Therefore we shall not fear, even though the heart be removed, and though I carried into the midst of the sea; though it’s waters roar and be troubled, though the mountains shake with that swelling. Psalm 46:1-3
From the end of the earth I will cry to You, and my heart is overwhelmed; lead me to the rock that is higher than I. Psalm 61:2
Therefore we do not lose heart. Even though our outward man is perishing, yet the inward man is being renewed day by day.
