The word of life is the message of salvation as it sets forth to us Christ, and goodness and blessedness by Him. Substantially it is that teaching which we have in the Scriptures; although, when Paul wrote, the New Testament was not yet a treasure of the Churches, and the "word of life" only echoed to and fro from teacher to taught, and from one disciple to another. Still, the teaching rested on the Old Testament Scriptures understood in the light of the testimony of Jesus; and it was controlled and guided by men speaking and writing in the Spirit. What it was therefore was very well known, and the influence of it as the seed of life eternal was felt. It was for Christians to _hold by it_, and to _hold it out_,--the expression used in ver. 16 may have either meaning; and virtually both senses are here. In order to give light there must be life. And Christian life depends on having in us the word, quick and powerful, which is to dwell in us richly in all wisdom and spiritual understanding. This must be the secret of blameless Christian lives; and so those who have this character will give light, as holding forth the word of life. The man's visible character itself does this. For while the word and message of life is to be owned, professed, in fit times proclaimed, yet the embodiment of it in the man is the main point here, the character being formed and the practice determined by the "word" believed. So also we are said to live by the faith of the Son of God. The life of faith on Him, is the life of having and holding forth His word. Here, as everywhere, our Lord goes first. The Apostle John, speaking in his Gospel of the Eternal Word, tells us that in Him was life, and the life was the light of men. It was not merely a doctrine of light; the life was the light. As He lived, in His whole being, in His acting and suffering, in His coming and staying and departing, in His Person and in His discharge of every office, He manifested the Father. Still we find it so; as we contemplate Him, as His words leads us to Himself, we behold the glory, the radiance of grace and truth. Now His people are made like Him. They too, through the word of life, become partakers of true life. This life does not dwell in them as it does in their Lord, for He is its original seat and source; hence they are not the light of the world in the same sense in which He is so. Still they are luminaries, they are stars in the world. By manifesting the genuine influence of the word of life which dwells in them, they do make manifest in the world what truth and purity and salvation are. This is their calling; and, in a measure, it is their attainment. The view of the matter given here may be compared with that in 2 Cor. iii. 4. Christ, the Father's Word, may also be regarded as the Father's living Epistle. Then those who behold Him, and drink in the significance of this message, are also themselves, in their turn, Epistles of Christ, known and read of all men.
