If I were asked to teach a class, I think the topic I would like to select for a 6 week course would be:
The Holiness of God
This also could be part of the "Romans Revolution" on the White Horse Inn.
Below would be a kind of Outline or a brief synopsis of the class information.
"The Lord is righteous in all His ways."
God’s holiness is evident in everything He does, particularly in creation, the law, judgment, and salvation.
The whole purpose of the Old Testament is to reveal the holiness and righteousness of God, who is utterly perfect and pure. In fact, the Hebrew word for "holy" is used more than 600 times in the Old Testament to indicate moral perfection.
What are some areas in which we see God’s holiness? First, we see it in the original perfection of His creation: "God saw all that He had made, and behold, it was very good" (Gen. 1:31). All of creation was in tune with God’s holy character.
Later God laid down His righteous, moral law for Israel. In it He gave rules about worship and society. He prescribed penalties for murder, adultery, and stealing. He condemned lying, coveting, and many other sins. There were many rules, but they revealed a God who is infinitely right and without error, flaw, or tolerance for sin. The law showed God’s character: "The Law is holy, and the commandment is holy and righteous and good" (Rom. 7:12).
God’s holiness will ultimately be demonstrated "when the Lord Jesus shall be revealed from heaven with His mighty angels in flaming fire, dealing out retribution to those who do not know God and to those who do not obey the gospel of our Lord Jesus. And these will pay the penalty of eternal destruction, away from the presence of the Lord and from the glory of His power" (2 Thess. 1:7–9). His judgment on sin is a reflection of His holiness; He must punish it.
Perhaps the supreme expression of God’s holiness is seen in sending His Son to die on the cross (cf. Rom. 8:3–4). God paid the highest price, but it was the only price that could satisfy His holiness. Jesus Christ is Himself "the Holy and Righteous One" (Acts 3:14); so only He could "put away sin by the sacrifice of Himself" (Heb. 9:26). God’s holiness is so infinite, and our unholiness is so great, that only the sacrifice of the God-man could pay for the enormity of our sin.
Suggestions for Prayer: Thank God that He sent His Son to die for our sins, so we could be "holy and blameless before Him" (Eph. 1:4).
For Further Study: Some of God’s laws for the Israelites are given in Exodus 21–23. Note in particular the penalties for breaking these laws. What does this passage teach you about God’s character?
