43 For there is no good tree which produces corrupt fruit, nor a corrupt tree which produces good fruit; 44 for every tree is known by its own fruit, for figs are not gathered from thorns, nor grapes vintaged from a bramble. 45 The good man, out of the good treasure of his heart, brings forth good; and the wicked [man] out of the wicked, brings forth what is wicked: for out of the abundance of the heart his mouth speaks.
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.
