"Prayer without meditation on the Word of God will disintegrate into humanistic spirituality. It will simply reflect our own fallen ideas and feelings - not God's. And meditation, without the humility of desperate prayer, will create proud legalism or hopeless despair. Without prayer we will try to fulfill the Word in our strength and think we are succeeding and so we become proud Pharisees; or we will realize that we are not succeeding and give up in despair." ~ John Piper
