Winston Churchill said when all was dark and evil looked like it would surely triumph, "Never give in. Never give in. Never, never, never, never--in nothing, great or small, large or petty--never give in, except to convictions of honor and good sense. Never yield to force. Never yield to the apparently overwhelming might of the enemy."
If you're in this place of desperation, reach for God's word. He will give you strength through it. It is supernatural. It is spiritual food. It is the drink your weary soul needs.
"And call upon Me in the day of trouble; I shall rescue you, and you will honor Me . . . He who offers a sacrifice of thanksgiving honors Me; And to him who orders his way aright I shall show the salvation of God." Psalm 50: 15, 23
"Behold, Thou dost desire truth in the innermost being, And in the hidden part Thou wilt make me know wisdom." Psalm 51:6
"Behold, God is my helper. The LORD is the sustanier of my soul." Psalm 54:4
Glory! God is here. Don't give up. Please don't give up. Hold on a bit more. The sun is going to rise. You will see victory.
