The Soldier of The Cross must live by prayer.
And of course, without the fresh taking in of God's Word, there is no effectiveness in prayer because there can be no Holy Spirit led agreement with God.
I once heard A. W, Tozer say that he would not consider attending even a committee meeting without preparing his heart in prayer. How remarkably easy it is to sachet through the day moving from one thing to the next, all the while operating in dim light and barely able to hear.
Prayerfully going through the day does not mean that there must be a little ceremony over each activity or encounter. There does however, need to be a commitment of the day in prayer and an affirmatively stated availability to be a living sacrifice. A stated desire to take up The Cross and follow Him. A request to be changed into His likeness, whatever it takes.
Prayer leads to more prayer. Prayer opens the door and He comes in to sup.
Where He is, there is always healing.
Where He is, there is Light.
Where He is, there are ears to hear.
Where He is, sin is exposed.
Where He is the Divine fire burns away what has to go.
Soldier, pray.
Aloud, and in the language of your heart - your every day language.
