John 15:22 If I had not come and spoken unto them, they had not had sin: but now they have no cloke for their sin.
Matthew Henry Commentary:
The aggravated guilt which those lie under to whom Christ has come and spoken in vain, whom he has called and invited in vain, with whom he has reasoned and pleaded in vain; They have no cloak for their sin; they are altogether inexcusable, and in the judgment day will be speechless, and will not have a word to say for themselves. Note, The clearer and fuller the discoveries are which are made to us of the grace and truth of Jesus Christ, the more is said to us that is convincing and endearing, the greater is our sin if we do not love him and believe in him. The word of Christ strips sin of its cloak, that it may appear sin.
