A great excerpt from a Prayer-walking guide by Dr. Dan R. Crawford; Professor of Evangelism & Spiritual Formation at Southwestern Baptist Theological Seminary;
Paul reminded us, “Though we walk in the flesh, we do not war according to the flesh, for the weapons of our warfare are not of the flesh, but divinely powerful for the destruction of fortresses.” (II Corinthians 10:3-4). The key phrase is not “the destruction of fortresses” but “divinely powerful.” You cannot war with Satan in your own strength and you certainly can’t singlehandedly destroy his fortresses. James instructs believers to, “Submit therefore to God. Resist the devil and he will flee from you.” (James 4:7).
You are not to command Satan, you are to resist him. Why would you want to talk to Satan, demanding that he refrain from some activity or remove himself from some place, when you have access to One infinitely more powerful and authoritative than Satan? So, don’t talk to Satan, talk to God about Satan. Don’t look for a demon behind every bush. Look for the evidences of God all around you. Don’t press the enemy, praise the victor.
In preparation for opposition you may want to pray about (or pray-on) your armor, “that you may be able to resist in the evil day, and. . . . stand firm” (Ephesians 6:13). Again, you may note that five of the six pieces of armor are defensive while only the Word of God is for offense. Pray on truth, righteousness, peace, faith, salvation, and the Word of God (Ephesians 6:14-17) and “with prayer and petition pray at all times in the Spirit…” (Ephesians 6:18).
Above all remember, “Do not fear or be dismayed. . . for the battle is not yours but God’s” (II Chronicles 20:15).
