Powerful prayer requires the Belt of Truth, because we need protection from all the false accusations that assail us. Our own doubts lie to us. Also, fear, worry, anger, bitterness, voices not known for truth-telling, block prayer. They oppose faith and drown hope.
The Lord Almighty not only fights for us, He also teaches us to fight. He gives us offensive weapons that He empowers to be mighty for the taking down of the enemy’s strongholds. So, we need to get busy!
