It is truly amazing that people can stand so steadfast in what they know. Doctrine and knowledge are extremely important in the Christian faith; however, strength in the inner man is different from knowledge in the outer man. How often do people live in the knowledge of past moments, of doctrine, or in clear-cut objective facts of knowledge? Thank God for a prayer such as Paul's in Ephesians 3. He prayed that Christ may dwell in our hearts. Christ lives in hearts to take us beyond the letter of the objective into the power of the subjective inner man.
When we are strengthened with might in the inner man, this gives us a life that reveals to our hearts the breadth and length and depth and height of God's love. The Gospel is the news of such a life. It is not in word only but in power (1 Corinthians 4:20). It is not objective alone, but a subjective life based upon faith in the objective truths to grant us knowledge that goes beyond knowledge. What I know objectively today without subjective power can never take me beyond what another knows objectively. We may agree on all the facts, but never experience the oneness that only Christ dwelling in our hearts can give.
This love, through the power of the Holy Spirit, takes us far beyond the knowledge of the breadth, length, depth and height as we live in it by faith. Although we do not fall away from what we know, we experience a love that goes beyond what we know so that we might know Him in whom are all unsearchable riches. This is the Mystery of the ages.
