Leviticus 20:7 - Consecrate yourselves and be holy

Consecrate yourselves and be holy, because I am the LORD your God.

Sanctify yourselves therefore, and be ye holy: for I am the LORD your God.

You shall consecrate yourselves therefore and be holy, for I am the LORD your God.

Leviticus 20:7

Commentary

Originating in God's nature, holiness is a unique quality of His character. The Bible emphasizes this divine attribute. "Who is like you, O Lord?" (Ex. 15:11). "There is none holy like the Lord" (1 Sam. 2:2). "Who shall not fear You, O Lord . . . For You alone are holy" (Rev. 15:4). God's high expectations of His people flow out of His own holy nature: "You shall be to me a kingdom of priests and a holy nation" (Ex. 19:6); "You shall be holy, for I the Lord your God am holy" (Lev. 19:2).
Jesus was the personification of holiness; He reinforced God's demands for holiness by insisting that His disciples have a higher quality and degree of righteousness than that of the scribes and Pharisees (Matt. 5:20). Like Amos and Hosea, Jesus appealed for more than ceremonial holiness: "I desire mercy and not sacrifice" (Hos. 6:6; Matt. 12:7). The theme of sanctification, or growing into God's likeness and being consecrated for His use, is prominent throughout the Bible. Like Jesus, the apostles taught that sanctification, or true holiness, expressed itself in patient and loving service while awaiting the Lord's return.

Revelation 1:8 - I am Alpha and Omega, the beginning and the ending

"I am the Alpha and the Omega," says the Lord God, "who is, and who was, and who is to come, the Almighty."

I am Alpha and Omega, the beginning and the ending, saith the Lord, which is, and which was, and which is to come, the Almighty.

"I am the Alpha and the Omega," says the Lord God, "who is and who was and who is to come, the Almighty."

Revelation 1:8

Commentary

There is a change of speaker. The Lord Jesus introduces Himself as the Alpha and the Omega (the first and last letters of the Greek alphabet), the Beginning and the End. He spans time and eternity, and exhausts the vocabulary of excellence. He is the source and goal of creation, and it is He who began and will end the divine program in the world. He is and was and is to come, eternal in His being and the Almighty in power. (1:8)
