For they shall eat the fruit of their doings— The certain consequence of righteousness is, by the divine determination, happiness either in this world or the next; as the contrary is the certain consequence of wickedness, Isaiah 3:11. This is an admirable sentence to support the souls of the pious, amidst all the troubles of this life; God will not forsake those who truly love and serve him. This reason teaches us, the experience of all times confirms, and it is the constant and comfortable doctrine of the word of God. The event must and will be happy to the good man.
