Pulpit Commentary
Pulpit CommentaryVerse 17. - If ye know these things, blessed are ye if ye do them. Knowing and doing are often perilously divorced (cf. Matthew 7:21, etc.; Luke 6:46; Luke 12:47; and James 1:25). The sublime principle by itself may be something, but if it be never put into practice, the last great beatitude is forfeited. Mere admiration of an ethical or a Christian principle degenerating into a heartless and fruitless ceremony is hardening to the heart and deadening to the conscience. The same truths had been taught independently of parable and symbol, in Matthew 23:8-12; Matthew 20:28.
Ellicott's Commentary
Ellicott's Commentary for English Readers(17) If ye know these things, happy are ye if ye do them.--The first clause of this verse assumes their knowledge of the things which He had been teaching them (John 13:13-17). They were, indeed, old lessons taught before in word, and now taught in act and word.The second clause makes their blessedness depend upon their combining action with knowledge. They had known the truth before, but their knowledge had not profited them, and they needed on this very day to be taught them again.
