DON'T STOP UNTIL THERE'S A CHANGE!
"…The earnest (heartfelt, continued) prayer of a righteous man makes tremendous power available [dynamic in its working]" (James 5:16b AMP).
Sometimes when you have a matter to settle or you desire a change in a situation you don't have full jurisdiction over, you have to continue in prayer until the change comes. Now, this doesn't negate faith nor mean you're unbelieving. Actually, the reason you choose not to give up or shift grounds is because you’re acting your faith.
Many are too used to praying "emergency prayers" that don't work. They wait until the pressure mounts and then start pushing panic-buttons and praying fast prayers for fast answers. But Elijah knew better. We read in our opening scripture what he did when he wanted a miracle: he cast himself down upon the earth and put his head between his knees, praying heartfelt, continued prayer (1 Kings 18:42). He prayed until he got a miracle.
You must have the willingness to pray with all your heart and continue in prayer until you have the note of victory in your spirit. You might ask, "But when do I stop?" You stop when you "know that you know" in your spirit (not in your head) that it’s done! Remember, this is different from the prayer of faith, where you pray only once and don’t have to go back to pray again about the same thing.
