Psalm 18: 28You, O Lord, keep my lamp burning; my God turns my darkness into light. 29With your help I can advance against a troop; with my God I can scale a wall. 30As for God, his way is perfect; the word of the Lord is flawless.

God supplies our needs, betters our circumstances (or sometimes our perception of them), overcomes our adversaries (physical and spiritual), and strengthens us to succeed in every situation.

With all of that, our role is to never doubt God and to have faith in His Word. We trust, seek, obey, and worship Him; He never fails (2 Timothy 2:13).
