Luke 6:37

All these sayings of Christ we had before in Matthew; some of them in ch. 7, others in other places. They were sayings that Christ often used; they needed only to be mentioned, it was easy to apply them. Grotius thinks that we need not be critical here in seeking for the coherence: they are golden sentences, like Solomon's proverbs or parables. Let us observe here, I. We ought to be very candid in our censures of others, because we need grains of allowance ourselves: "Therefore judge not others, because then you yourselves shall not be judged; therefore condemn not others, because then you yourselves shall not be condemned, Luk 6:37. Exercise towards others that charity which thinks no evil, which bears all things, believes and hopes all things; and then others will exercise that charity towards you. God will not judge and condemn you, men will not." They that are merciful to other people's names shall find others merciful to theirs. II. If we are of a giving and a forgiving spirit, we shall ourselves reap the benefit of it: Forgive and you shall be forgiven. If we forgive the injuries done to us by others, others will forgive our inadvertencies. If we forgive others' trespasses against us, God will forgive our trespasses against him. And he will be no less mindful of the liberal that devise liberal things (Luk 6:38): Give, and it shall be given to you.
