The children of Ephraim, being armed and carrying bows, turned back in the day of battle.
Ps. Ixxviii. 9.

Be thou strong, and very courageous.
Joshua i. 7

Go forward, Christian soldier.
Beneath His banner true!
The Lord Himself, thy Leader,
Shall all thy foes subdue.
His love foretells thy trials;
He knows thine hourly need;
He can with bread of heaven
Thy Minting spirit feed.
Lawrence Tuttiett.

WHILE there is left in you a trace of ill-temper, or of vanity, of pride, or of selfishness; while there is left in you a single sin, or germ of sin, you must not rest from the battle. God does not require from you to be sinless when you come before Him, but He does require you to be unceasing in your perseverance. He does not require that you shall never have fallen; but He does require unwearied efforts. He does not require you to win, but He does require you to fight.
Frederick Temple.

Still fight resolutely on, knowing that, in this spiritual combat, none is overcome but he who ceases to struggle and to trust in God.
Lorenzo Scupoli
