The most well known text of Scripture combining prayer and passion is found in James 5:16- “The effective [or fervent] prayer of a righteous man can accomplish much.” E. M. Bounds, in his chapter on this topic, makes an excellent point regarding the fervency we need to be pray in an effective manner.
To be absorbed in God’s will, to be so greatly in earnest about doing it that our whole being takes fire, is the qualifying condition of the man who would engage in effectual prayer.” (35)
This kind of engagement with reading God’s Word, seeing His will plainly, and seeking to be absorbed in doing it will lead to fervent prayer, both as a means of attaining this kind of lifestyle as well as a result of being so caught up with the things of God. And lest we mistake the reality of it, the will of God is that which is expressed in the Scriptures, specifically our sanctification or growth in Christ-likeness (Eph 5:17; 1 Thess 4:3; 5:16-18). And, to avoid another categorical error, this being absorbed with doing God’s will does not lead to self-absorption, but rather a passion to love God, serve others, and live in such a way as to make the glory of God go public throughout the world.
If our ultimate desire as Christians is to know God and make Him known for the glory of His name and the joy of our souls, it will require a deep-seated passion that is rooted in the truth of Scripture and expressing itself through obedient, fervent, faith-filled prayer. May we be red-hot in our devotion to God and may this come through in our prayers to Him.
