It is a truly blessed thing for the soul of man to see God. God is a spirit, and is not to be seen with the bodily eyes. The soul has those powers which are capable of apprehending objects, and especially spiritual objects, without looking through the windows of the outward senses. Jonathan Edwards writes:
God formerly delivered his law from Mount Sinai by an audible voice, with the sound of a trumpet, with the appearance of devouring fire, with thunders, and lightnings, and earthquakes. But the principal discoveries of God’s Word and will to mankind were reserved to be given by Jesus Christ, his own Son, and the Redeemer of men, who is the light of the world.
In this sermon of Christ, of which the text is a part, we hear him delivering the mind of God also from a mountain. Here is God speaking, as well as from mount Sinai, and as immediately, but after a very different manner. There God spake by a preternatural formation of sounds in the air. Here he becomes incarnate, takes on him our nature, and speaks, and converses with us, not in a preternatural, awful, and terrible manner, but familiarly as one of us. His face was beheld freely by all that were about him. His voice was human, without those terrors which made the children of Israel desire that God might speak to them immediately no more. And the revelation which he makes of God’s Word is more clear and perfect, and fuller of the discoveries of spiritual duties, of the spiritual nature of the command of God, of our spiritual and true happiness, and of mercy and grace to mankind. John 1:17, “For the law was given by Moses, but grace and truth came by Jesus Christ”. . . .
The truth which Christ teaches them in the text, that they were blessed who were pure in heart was a thing wholly beyond their conceptions. The Jews at this time placed almost the whole of religion in external things, in conformity to the rites and ceremonies of the Law of Moses. They laid great stress on tithing mint, and anise, and cumin, and on their traditions, as in washing hands before meat and the like. But they neglected the weightier matters of the law, and especially such as
respected holiness of heart. They took much more care to have clean hands, and a clean outside, than a clean heart, as Christ tells them, Mat. 23:25, 27, “Woe unto you, scribes and Pharisees, hypocrites! for ye make clean the outside of the cup and of the platter, but within ye are full of extortion and excess. Thou blind Pharisee, cleanse first that which is within the cup and platter that the outside of them may be clean also.”
We may observe concerning the words of the text:
I. That Christ pronounces the pure in heart, blessed. Christ here accommodates his instructions to the human nature. He knew that all mankind were in the pursuit of happiness, he has directed them in the true way to it, and he tells them what they must become in order to be blessed and happy.
II. He gives the reason why such are blessed, or wherein the blessedness of such consists, that they shall see God. It is probable the Jews supposed that it was a great privilege to see God, from those passages in the law, where there is an account of Moses’ earnestly desiring to see God’s glory; and from the account that is given of the seventy elders. . . .
From these words I shall derive two propositions:
First, it is a truly blessed thing to the soul of man to see God.
Second, to be pure in heart, is the certain and only way to attain to this blessedness. (“The Pure in Heart Blessed”)
