“Preparation for conflicts and for battle is an awareness of the presence of God [see Josh. 5]. It is a meeting with him and an ongoing awareness of His presence with us… when we subjectively make this the realization of our hearts, we are armed for conflict… God is present—that is one of the primary sanctifying awarenesses of life. And it arms us for power. He is here, and we need to believe it… that He’s here; sanctifying, ennobling, edifying, empowering awareness of the presence of God. How beautiful and how wonderful that is!” (Kent Hughes)
