The Psalmist says, "Truly God is good to Israel, even to such as are of a clean heart." (Psalm 73:1)
God is good to all, and "His tender mercies are over all His works." (Psalm 145:9)
But those who are clean of heart see and recognize His goodness.
"Israel" does not mean a class of people whom God has distinguished from all others by being good to them, but simply those who, by having clean hearts, have recognized and acknowledged the goodness of the Lord bestowed upon all.
Only the pure in heart can see God, (Matthew 5:8) and only they who see Him can know Him. We see God now with the eye of faith, and faith is that which purifies the heart. "purifying their hearts by faith." (Acts 15:9)
As soon as we believe what God has said, we shall know for ourselves that God is good, not only to the world in general, but to us.--Present Truth, September 27, 1894--Psalm 73:1.
