Now when we speak of one another as' faithful,' we mean that we adhere to our word; that we keep faith with men, that we discharge the obligations of our office or position, and that so we are trustworthy. We mean just the same things when we speak about the faithful God.
I suppose that the first thought that occurs to most of us when God is called faithful is that it means that He keeps His promise. That, of course, is included in the idea, but it is very noteworthy that this, which to most of us is the only meaning of the expression, is rarely its meaning in the New Testament. Out of all the cases in which the phrase occurs it only twice has reference to God's fulfilment of His spoken words; and these two instances both occur in the Epistle to the Hebrews, where we read: He is faithful that promised,' and' She judged Him faithful that promised.' Now it is a great truth that out of the darkness God has spoken; that, like some constitutional monarch, He has declared the principles of His government, and so has bound Himself by articulate expressions to follow out these in His dealings. He is not a despot; He is a King who has laid down the law to which He Himself will adhere. His promises hang out over the troubled stream of life, like boughs from the trees on the bank, for His half-drowned children to grasp at and to hold by.
But great as that thought of our God's fulfilment of His every word is, it does not go half way down to the depths of meaning in the New Testament use of the expression the faithful God.' For my text witnesses to a deeper meaning. He cannot deny Himself.' That is Paul's notion of the faithfulness of God; that His nature and character constitute for Him, if I may so say, a solemn obligation; that He is His own law; that He is bound by what He is, and that He never can be, in the smallest degree, anything contradictory to, or falling beneath, the level of His own equable, consistent, and uniform Self. As God, He must be true to the character of goodness and wisdom which the very name of God brings with it. We drop below our best selves; contradictory impulses and thoughts fight in our nature; the flesh lusteth against the Spirit, and the Spirit against the flesh. No man is always himself; God is always Himself. We are like the little brooks that are dried in drought and swelled in spate, are parched in summer and frozen in winter, but this great river is always bank-full, and always clear and always flowing. This ocean is tideless and has no ebb or flood; and you can look down into its deepest depths, and as far as the vision of the eye can go, all is clear and pure, and where vision fails, it is not that the ocean is dark but that the sense is limited. So John says, in his infanthe-angelic way, with a simplicity that is sublime, God is Light, and in Him is no darkness at all.' The sun has spots; it has, as astronomers tell us, a photosphere, an envelope that gives light, but possibly its core is black and dark. But that is not so with the true Light. God is faithful; He cannot deny Himself.'
Then there is another deep thought in the word which is recurrent in the various applications of the expression throughout the New Testament--that God's faithfulness implies that He is true, not only to His words, not only to Himself, but also to the trend and drift, so to speak, of His past acts. That thought is applied in the New Testament in two different ways. Peter says to the troubled disciples to whom he was writing, Commit the keeping of your souls to Him in well-doing, as unto a faithful Creator.' The fact of having made creatures binds God to certain obligations in regard to them, and He will discharge them. The other application of the idea of God's faithfulness is in reference to His past acts bearing on man's redemption. We find verses like these: Faithful is He that calleth you'; God is faithful by whom ye were called unto the fellowship of His Son.' The thought there is that, by the fact of His redeeming work, God has come under certain obligations to the persons who yield to the invitation that is wrapped up in the message and gifts of Christ and of Christ's Spirit, and that He will faithfully discharge these.
