Every believer when he is born again and is assured of an everlasting inheritance, is also miraculously, by the power of God, rescued from the domain of darkness and is transferred into the kingdom of God and of His Son. Paul in Colossians 1:13 writes, “For He rescued us from the domain of darkness, and transferred us to the kingdom of His beloved Son.”

This kingdom, though it is grand and glorious, is not visible; it is a spiritual kingdom and it is within us—within every believer (Lu. 17:21). Christ sits on His throne in our hearts, and He will lead us and instruct us in right living; but only if we allow Him to. Hence, all who are obedient sons of God are led by the Spirit of God (Rom. 8:14).

Now from time to time we will fall into sin; for we still have our sinful flesh. But we remain children of God who live in His kingdom, and because Christ has come into our heart and changed us—given us a new nature—we have His mind. Paul has written in 1 Corinthians 2:15-16,

But he who is spiritual appraises all things, yet he himself is appraised by no one. 16 For WHO HAS KNOWN THE MIND OF THE LORD, THAT HE WILL INSTRUCT HIM? But we have the mind of Christ.

And with our new mind and by the powerful strength of God in us and around us we are protected from the devil and all evil—but only if we use that protection. Paul, in Ephesians 6, speaks of this Christian protection as the armor of God. It is available to us if we put it on every day. It is the Christian’s daily and life-long attire.

One of the most powerful pieces of armor available to us is prayer. Paul writes that we are to “pray at all times in the Spirit” (Eph. 1:18). James also writes about prayer. He said, “If any of you lacks wisdom, let him ask of God, who gives to all generously and without reproach, and it will be given to him” (Ja. 1:5). But then he goes on to say that we must ask in faith without any doubting. And this is the key to living victoriously in the kingdom of God—having faith in God and in Christ without doubting. It is a life of trust in Him.
