It is impossible but offences will come - And they ever did and do come chiefly by Pharisees, that is, men who trust in themselves that they are righteous, and despise others. Mat 18:6; Mar 9:42.
If he sin against thee seven times in a day, and seven times in a day return, saying, I repent - That is, if he give sufficient proof that he does really repent, after having sinned ever so often, receive him just as if he had never sinned against thee. But this forgiveness is due only to real penitents. In a lower sense we are to forgive all, penitent or impenitent; (so as to bear them the sincerest good will, and to do them all the good we can;) and that not seven times only, but seventy times seven.
And he said, If ye had faith as a grain of mustard seed - If ye had the least measure of true faith, no instance of duty would be too hard for you. Ye would say to this sycamine tree - This seems to have been a kind of proverbial expression.
When ye have done all, say, We are unprofitable servants - For a man cannot profit God. Happy is he who judges himself an unprofitable servant: miserable is he whom God pronounces such. But though we are unprofitable to him, our serving him is not unprofitable to us. For he is pleased to give by his grace a value to our good works, which in consequence of his promise entitles us to an eternal reward.
Neither shall they say, Lo here, or lo there - This shall not be the language of those who are, or shall be sent by me, to declare the coming of my kingdom. For behold the kingdom of God is within or among you - Look not for it in distant times or remote places: it is now in the midst of you: it is come: it is present in the soul of every true believer: it is a spiritual kingdom, an internal principle. Wherever it exists, it exists in the heart.
The sense of this and the following verses is, Yet as great as the danger will be, do not seek to save your life by violating your conscience: if you do, you will surely lose it: whereas if you should lose it for my sake, you shall be paid with life everlasting. But the most probable way of preserving it now, is to be always ready to give it up: a peculiar Providence shall then watch over you, and put a difference between you and other men.
