“I am the Alpha and the Omega” [Note: These are the first and last letters of the Greek alphabet, and indicate “the beginning and the end” See 21:6], says the Lord God Almighty, who is [in the present], and who was [in the past] and who will come [in the future].
For [that class of] persons whom God knew beforehand He also predetermined to become conformed to the [spiritual] likeness of His Son, so that He could be the firstborn One among [His] many brothers [i.e., so He could be the preeminent example to all His followers. See Heb. 2:11].
God predetermined that we should be [considered] His adopted children through [fellowship with] Christ. This is what pleased God and is what He wanted,
For [all] creation [Note: “Creation” here refers to the material heavens and earth, and is personified through verse 23] is eagerly waiting for the children of God to be revealed [i.e., in their glorious state].
