Verse 13. Let us not therefore judge, etc. Since we are to give account of ourselves at the same tribunal; since we must be there on the same level, let us not suppose that we have a right here to sit in judgment on our fellow-Christians.

But judge this rather. If disposed to judge, let us be employed in a better kind of judging; let us come to a determination not to injure the cause of Christ. This is an instance of the happy turn which the apostle would give to a discussion. Some men have an irresistible propensity to sit in judgment, to pronounce opinions. Let them make good use of that. It will be well to exercise it on that which can do no injury, and which may turn to good account. Instead of forming a judgment about others, let the man form a determination about his own conduct.

That no man, etc. A stumbling-block literally means anything laid in a man's path, over which he may fail. In the Scriptures, however, the word is used commonly in a figurative sense, to denote anything which shall cause him to sin, as sin is often represented by falling. See Barnes "Mt 5:29".

And the passage means, that we should resolve to act so as not by any means to be the occasion of leading our brethren into sin, either by our example, or by a severe and harsh judgment, provoking them to anger, or exciting jealousies, and envyings, and suspicions. No better rule than this could be given to promote peace. If every Christian, instead of judging his brethren severely, would resolve that he would so live as to promote peace, and so as not to lead others into sin, it would tend more, perhaps, than any other thing to advance the harmony and purity of the church of Christ.
