43 For no good tree gives bad fruit, and no bad tree gives good fruit. 44 For every tree is judged by its fruit. Men do not get figs from thorns, or grapes from blackberry plants. 45 The good man, out of the good store of his heart, gives good things; and the evil man, out of his evil store, gives evil: for out of the full store of the heart come the words of the mouth.
Matthew Henry's Commentary on Luke 6:43-45
Commentary on Luke 6:37-49
(Read Luke 6:37-49)
All these sayings Christ often used; it was easy to apply them. We ought to be very careful when we blame others; for we need allowance ourselves. If we are of a giving and a forgiving spirit, we shall ourselves reap the benefit. Though full and exact returns are made in another world, not in this world, yet Providence does what should encourage us in doing good. Those who follow the multitude to do evil, follow in the broad way that leads to destruction. The tree is known by its fruits; may the word of Christ be so grafted in our hearts, that we may be fruitful in every good word and work. And what the mouth commonly speaks, generally agrees with what is most in the heart. Those only make sure work for their souls and eternity, and take the course that will profit in a trying time, who think, speak, and act according to the words of Christ. Those who take pains in religion, found their hope upon Christ, who is the Rock of Ages, and other foundation can no man lay. In death and judgment they are safe, being kept by the power of Christ through faith unto salvation, and they shall never perish.
