Grace is the only thing against which the devil has no defence. If you are living by your self-effort to earn God’s approval, the devil has power over you because he can always point to something that you have not done. This gives him dominion over you.
If you claim God’s protection and healing based on what you have done, the devil, who is a master accuser, just has to point to one of your failures, and all your faith implodes. You will disqualify yourself mentally and inwardly from receiving whatever you might be trusting the Lord for. It was the grace of God that crush Satan under our feets as believers.
But grace qualifies us for protection. Because Jesus paid the price, we who are in Him have a right to walk in divine health and protection. When the devil accuses you, saying, “How dare you believe God for protection? Just have to point to Jesus’ blood, which has paid for all your failures. With grace as your basis, the God of peace can reign over your fears and impart to you unshakable faith for His protection!
Something else happens when you understand His grace, you will also grow in your understanding of how perfectly loved you are by your Father in heaven. God so loved you and me, He sent His only begotten Son to die on the cross on our behalf, carrying all our sins upon His own body so that today, we can come boldly to His throne of grace, which is full of grace and truth.
