To this argument there is, for the natural man, a ready answer. It by no means follows, he will say, that because the Gospel is devoid of ambiguity or inconsistency, equivocation and insincerity must be unknown to its preachers. A man may proclaim the true Gospel and in his other dealings be far from a true man. Experience justifies this reply; and yet it does not invalidate Paul's argument. That argument is good for the case in which it is applied. It might be _repeated_ by a hypocrite, but no hypocrite could ever have _invented_ it. It bears, indeed, a striking because an unintentional testimony to the height at which Paul habitually lived, and to his unqualified identification of himself with his apostolic calling. If a man has ten interests in life, more or less divergent, he may have as many inconsistencies in his behaviour; but if he has said with St. Paul, "This one thing I do," and if the one thing which absorbs his very soul is an unceasing testimony to the truth and faithfulness of God, then it is utterly incredible that he should be a false and faithless man. The work which claims him for its own with this absolute authority will seal him with its own greatness, its own simplicity and truth. He will not use levity. The things which he purposes, he will not purpose according to the flesh. He will not be guided by considerations perpetually varying, except in the point of being all alike selfish. He will not be a Yes and No man, whom nobody can trust. The argumentative force of the passage being admitted, its doctrinal import deserves attention. The Gospel--which is identified with God's Son, Jesus Christ--is here described as a mighty affirmation. It is not Yes and No, a message full of inconsistencies, or ambiguities, a proclamation the sense of which no one can ever be sure he has grasped. In it (ἐν αὐτῷ means "in Christ") the everlasting Yea has found place. The perfect tense (γέγονεν) means that this grand affirmation has come to us, and is with us, for good and all. What it was and continued to be in Paul's time, it is to this day. It is in this positive, definite, unmistakable character that the strength of the Gospel lies. What a man cannot know, cannot seize, cannot tell, he cannot preach. The refutation of popular errors, even in theology, is not gospel; the criticism of traditional theories, even about Scripture, is not gospel; the intellectual "economy," with which a clever man in a dubious position uses language about the Bible or its doctrines which to the simple means Yes, and to the subtle qualifies the Yes enormously, is not gospel. There is no strength in any of these things. Dealing in them does not make character simple, sincere, massive, Christian. When they stamp themselves on the soul, the result is not one to which we could make the appeal which Paul makes here. If we have any gospel at all, it is because there are things which stand for us above all doubts, truths so sure that we cannot question them,
