A warning against self-deceit.
The high but false estimate that men may form of themselves is the great hindrance to this mutual burden-bearing. Consider—
I. THE STRANGENESS OF SELF-DECEPTION. It is not remarkable that a man should be the dupe of others, but strange that he should be the dupe of himself. Yet there are many who think themselves to be something when they are nothing—partly from the want of self-knowledge; partly from the deceitfulness and pride of the human heart; partly from the fallacious habit of measuring themselves by the attainments of others; partly, too, from the influence of false teachings.
II. ITS EVIL EFFECTS UPON THE MAN HIMSELF. He deceives himself, but he cannot deceive either God or man. It is a fatal delusion while it lasts, for it stands in the way of all improvement. He lives in a fool's paradise. If he had once discovered that he was nothing he would be put in the way of getting the foundation rightly laid, and he would be the more likely to have points of sympathy with the outcast and fallen. The sense of our own weakness is the best motive to an indulgent consideration for others.
III. ITS EVIL EFFECTS AS REGARDS OTHERS. This is the crowning idea of the passage. The self-deceived man is incapable of bearing others' burdens, in fact, the imagination of superior piety leads him to be harsh and censorious and overbearing to others. There are sects in our day which pretend to a deeper communion with God than other Christians, and they are only remarkable for a censorious pride which kills love. The self-deceived man thinks meanly of others' attainments, in opposition to the gospel temper, which counsels Christians "in lowliness of mind to think others better than themselves;" while he takes no delight in their graces or gifts, and will accept neither instruction nor correction from others. He seems self-supporting and self-contained, exempt from frailty, sin, and sorrow, and therefore cares nothing for the sins or the sorrows of others. It is only the disposition that can say, "Not I, but the grace of God in me," that will be ready for that mutual burden-bearing which conduces so much to the comfort and cohesion of Christian society.
