‘We are involved in spiritual warfare but we are not fighting for victory, we are fighting from victory because this battle has already been won, and we are on the winning side, but Satan is still a powerful enemy. Satan lost his authority but he didn’t lose his power. The truth we need to realise, and the truth that will set us free, is that Satan no longer has authority. That is the key. Authority is the right to use the power you possess. In order for Satan to use his power in your life, he has to keep you from functioning underneath your authority because his power is only effective when he has the right to use it – that is, when we relinquish our authority and allow him to have power over us.’
