(2) But this Divine gift is only possible by means of a simple yet important condition. It is "in the full knowledge of Him." The word rendered "knowledge" is characteristic of these prison epistles, and always means "full knowledge," the mature experience of the spiritual man. It is invariably connected with God; it refers to the deep, growing, ripening consciousness which comes from personal fellowship with Him. Philosophy can only say "Know thyself," but Scripture says, "Know God." This is how wisdom and revelation become ours, and Christian history and experience testify abundantly to the simple yet remarkable fact of spiritual insight and moral understanding which are due solely to fellowship with God. Nothing is more striking than the fact of a deep, spiritual apprehension and appreciation which are independent of intellectual conception and verbal expression. Believers can have a true spiritual consciousness of God without the possession of great capacity or attainments. Many whose natural education and intellectual opportunities have been slight have had this spiritual perception in an uncommon degree, and it always marks the spiritually ripe Christian. It is not the one whose intellectual knowledge is critical, scholarly, and profound, but he whose spiritual insight is suffused with grace, love, and fellowship. This does not mean that natural knowledge or culture is to be despised or avoided as evil, but that the two kinds of knowledge should be carefully distinguished. The Christian Church has at least for the last three hundred years set great store by knowledge and science, but deeper than all this is the spiritual instinct, insight, knowledge, and illumination which constitute the supreme requirement of the true Christian life. We can see this spiritual perception in its various stages in several passages of the New Testament. We have seen how St. John divides believers into three classes (1 John ii. 12-14). But while in his repetition the Apostle can vary the description of the "children" and the "young men," when he has to speak the second time of the "fathers" he has nothing new to say, for they cannot be otherwise or more fully described than as those who "know Him Who is from the beginning."
