God's Promises are the Key to the Dungeon of Despair

⁵ Let your conduct be without covetousness; be content with such things as you have. For He Himself has said, “I will never leave you nor forsake you.” (Hebrews 13:5, New King James Version)

⁹ 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, New King James Version)

Cling to these promises as you press on.
