Revelation 1:8; Which Was, Which, Is, Which Is to Come
Revelation 1:8 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.
The Lord Jesus speaks these words, He is God Almighty. He came as a Suffering Servant in His first coming. But in His Second Coming, He will come as a Judge. Jesus was with the Father in the beginning of no beginnings.
The Proverbs describe well this truth in Proverbs 8:22-26 – 22 The LORD (God the Father) possessed (co-existed with) me (Wisdom, Jesus) in the beginning of His way, before His works of old. 23 I (Wisdom, Jesus) was set up from everlasting (there was never a time the Son did not exist as God), from the beginning, or ever the earth was. (Before all His works, Jesus was with the Father.) 24 When there were no depths, I was brought forth; when there were no fountains abounding with water. 25 Before the mountains were settled, before the hills was I brought forth: 26 While as yet he had not made the earth, nor the fields, nor the highest part of the dust of the world.
God the Father and His only begotten Son Jesus Christ personified as Wisdom that was with Jehovah (the LORD) in eternity past before the world was ever made (Prov. 8:22-26). It teaches the eternal relation of the Son (Wisdom) to the Father.
