Think not that I am come to destroy the law, or the prophets: I am not come to destroy, but to fulfil. Matt. 5:17.
The law is a transcript of God's character. The same things that are said about God are said about His law. God is truth (John 14:6). His law is truth (Ps. 119:142). God is perfect (Matt. 5:48). His law is perfect (Ps. 19:7). God is holy (Isa. 6:3). His law is holy (Rom. 12:7). God is unchangeable (Mal. 3:6). The law is unchangeable (Matt. 5:18). God is spiritual (John 4:24). His commandments are spiritual (Rom. 4:17). God is forever (Ps. 9:7; 90:2). His law is forever (Ps. 111:7; 119:44).
This means that it always has been and always will be wrong to kill and steal and lie and covet and take God's name in vain and all the rest of it. There is no time when the commandments will be changed, by situational ethics or anything else. Why? Because the Ten Commandments are what God is, and what Jesus is.
A woman goes to the dry-goods store for material to make a dress. She rummages through the bolts of cloth until she finds one that appeals to her. She pauses, fingers the cloth, holds if up to the light. The proprietor comes by and says, "Do you like that cloth?" "Well," she says, "I think so. I was just trying to visualize how it would look made up into a dress." The shopkeeper takes her to the front window and points out a dress made from the same cloth. And the woman says, "In the bolt it was beautiful. But made into a dress it is even more beautiful! I'll take it!"
We look as the Ten Commandments and realize the wisdom there revealed. We admit that not a single improvement could be made--except for one. To see the Ten Commandments made up into a life. Whereas these principles were beautiful on tables of stone, they are much more beautiful made up into a life--the life of Jesus. Jesus reveals the Ten Commandments. He came to this earth, and through depending moment by moment upon His Father's power, kept every one of the Ten Commandments perfectly. He offers to us today the same power that He had. Through dependence upon Him we may reveal to the world the beauty of character that will bring glory to Him. The Ten Commandments may be made up into our lives as well.
