God has given us prayer as a wartime walkie-talkie so that we can call headquarters for everything we need as the kingdom of Christ advances in the world. Prayer gives us the significance of front-line forces, and gives God the glory of a limitless Provider. The one who gives the power gets the glory. Thus prayer safeguards the supremacy of God in missions while linking us with endless grace for every need.
John PiperLoving God with all our mind means that our thinking is wholly engaged to do all it can to awaken and express the heartfelt fullness of treasuring God above all things.
John PiperI sometimes fear that we have so redefined conversion in terms of human decisions and have so removed any necessity of the experience of God’s Spirit, that many people think they are saved when in fact they only have Christian ideas in their head not spiritual power in their heart.
