But utterance is well backed by knowledge. Not always has it been remembered that Paul recognises knowledge as a gift of God. Often, on the contrary, has the determination to satisfy the intellect with Christian truth been reprehended as idle and even wicked. To the Corinthians the Christian revelation was new, and inquiring minds, could not but endeavour to harmonize the various facts it conveyed. This attempt to understand Christianity was approved. The exercise of the human reason upon Divine things was encouraged. The faith which accepted testimony was a gift of God, but so also was the knowledge which sought to recommend the contents of this testimony to the human mind.
But however rich in endowments the Corinthians were, they could not but feel, in common with all other men, that no endowment can lift us above the necessity of conflict with sin or put us beyond the hazard which that conflict entails. In point of fact, richly endowed men are often most exposed to temptation, and feel more keenly than others the real hazard of human life. Paul therefore concludes this brief introduction by assigning the reason of his assurance that they will be blameless in the day of Christ; and that reason is that God is in the matter: "God is faithful, by whom ye were called unto the fellowship of His Son Jesus Christ our Lord." God calls us with a purpose in view, and is faithful to that purpose. He calls us to the fellowship of Christ that we may learn of Him and become suitable agents to carry out the whole will of Christ. To fear that, notwithstanding our hearty desire to become of Christ's mind and notwithstanding all our efforts to enter more deeply into His fellowship, we shall yet fail, is to reflect upon God as either insincere in His call or inconstant. The gifts and calling of God are without repentance. They are not revoked on further consideration. God's invitation comes to us, and is not withdrawn, even though it is not met with the hearty acceptance it deserves. All our obstinacy in sin, all our blindness to our true advantage, all our lack of anything like generous self-devotion, all our frivolity, and folly, and worldliness, are understood before the call is given. By calling us into the fellowship of His Son God guarantees to us the possibility of our entering into that fellowship and of becoming fit for it.
Let us then revive our hopes and renew our belief in the worth of life by remembering that we are called to the fellowship of Jesus Christ. This is satisfying; all else that calls us in life is defective and incomplete. Without this fellowship with what is holy and eternal, all we find in life seems trivial or is embittered to us by the fear of loss. In worldly pursuits there is excitement; but when the fire burns out, and the cold ashes remain, chill and blank desolation is the portion of the man whose all has been the world. We cannot reasonably and deliberately choose the world; we may be carried away by greed, or carnality, or earthliness to seek its pleasures, but our reason and our better nature cannot approve the choice. Still less does our reason approve that what we cannot deliberately choose we should yet allow ourselves to be governed by and actually join in fellowship of the closest kind. Believe in God's call, listen to it, strive to maintain yourself in the fellowship of Christ, and every year will tell you that God, who has called you, is faithful and is bringing you nearer and nearer to what is stable, happy, and satisfying.
