God helped the Reubenites, Gadites, and men of Manasseh when they waged war because they pleaded for His help in the midst of the battle. He answered their prayers “because they trusted in him.”
In spiritual warfare you must remember two things. First, you need to pray constantly while the battle is raging. Assemble a group who will commit to pray continually until the battle turns and the victory is won. Second, remember that the Lord is fighting against the enemy (1 Chronicles 5:22). Recognize that it is really not your battle, but the Lord’s.
God and Satan are irreconcilable enemies, and God is as interested in your victory as you are. When you realize that God is actually fighting your battle, you will say to the enemy as David did to Goliath, “The Lord does not need weapons to rescue his people. It is his battle, not ours. The Lord will give you to us!” (1 Samuel 17:47).
Many times you lose spiritual battles when you start complaining, whining, and muttering about your defeat. “Those who love to talk will experience the consequences, for the tongue can kill or nourish life” (Proverbs 18:21). Guard your tongue, and every day proclaim, “The battle is the Lord’s.” He will not let you be defeated!
