The Commands of Christ-12e
The focus of the “second” commandment—“You shall love your neighbor as yourself” (Matt. 22:39)—is not on whether the receiver of love is an enemy or a friend, but on whether the one who loves desires the neighbor’s good as he desires his own. Its importance is seen by the two stupendous things that lie on either side of it. On one side is the greatest commandment in the Word of God—“You shall love the Lord your God with all your heart and with all your soul and with all your mind.” On the other side is the assertion that everything written in the Law and the Prophets hangs on these two commandments. We are in the company of incomparable superlatives—the two greatest commandments in the entire Word of God, and all of that Word hanging on them. We should take off our shoes in reverence here. There are few texts of Scripture greater than this.
The second commandment seems to me to be an overwhelming commandment. It seems to demand that I tear the skin off my body and wrap it around another person so that I feel that I am that other person; and all the longings that I have for my own safety and health and success and happiness I now feel for that other person as though he were me. It is an absolutely staggering commandment. If this is what it means, then something unbelievably powerful and earthshaking and reconstructing and overturning and upending will have to happen in our souls. Something supernatural. Something well beyond what self-preserving, self-enhancing, self-exalting, self-esteeming, self-advancing, fallen human beings like me can do on their own.
Underlining the greatness of this commandment is the fact that it is surpassed only by the command to love God with our whole being.
Pure in heart refers to someone who is authentically righteous. The Pharisees faked righteousness by outward behaviors, just like people can fake righteousness with good works today. But true purity of heart is given to the person who mourns his or her spiritual bankruptcy and hungers and thirsts for God’s righteousness in personal relationship with Christ.
There is a deep desire in every human heart to see God. Like Moses, we want to see God in all His glory (Ex 33:18).
