I am concerned and disgusted by how many are being influenced by the heresy of Arianism (believing Jesus is the Son of God but less than God, not equal with the Father, and/or a created being).
These folks are dangerous and unbiblical regardless of how much emphasis they place upon holiness, spirituality, etc. It is heresy.
Jesus is not the Father and is distinct from the Father but He is not less than the Father. He is fully God.
Revelation 1:7-8 is obviously a reference to Jesus Christ. He says of Himself:
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.
In Revelation 1:11 He says of Himself: I am Alpha and Omega, the first and the last:
In Revelation 1:17-18 He says of Himself: Fear not; I am the first and the last:
I am He that liveth, and was dead; and, behold, I am alive forevermore, Amen; and have the keys of hell and of death.
Revelation 2:8- These things saith the first and the last, which was dead, and is alive;
These are all obvious references to Jesus Christ as He is the one who was dead and now alive.
Revelation 21:6- I am Alpha and Omega, the beginning and the end.
Revelation 22:12-13 is an obvious reference to Jesus Christ as He is the one coming back to judge every man according to His work (Matthew 16:27).
Revelation 22:13- I am Alpha and Omega, the beginning and the end, the first and the last.
In each of these verses Jesus is quoting Isaiah 44:6 and referring to the One being spoken of:
Isaiah 44:6- Thus saith the Lord the King of Israel, and His redeemer the Lord of hosts; I am the first, and I am the last; and beside me THERE IS NO GOD.
Each time Jesus refers to Himself as Alpha and Omega the first and the last He is referring to Himself as the One true God the One spoken of in Isaiah 44:6.
Also when Jesus refers to Himself in Revelation 1:8 as “the Lord, which is, and which was, and which is to come, the Almighty” He is referring to Himself as the One sitting upon the throne in Revelation 4:2-8.
Revelation 4:8- And the four beasts had each of them six wings about him; and they were full of eyes within: and they rest not day and night, saying, Holy, holy, holy, LORD GOD ALMIGHTY, WHICH WAS, AND IS, AND IS TO COME.
Jesus speaking in Revelation 1:8 is referring to Himself as the One sitting upon the throne in Revelation 4:8. This is also a direct reference and quote referring to the One sitting upon the throne in Isaiah 6:1-3:
Isaiah 6:3- And one cried unto another, and said, Holy, holy, holy is the Lord of hosts: the whole earth is full of His glory.
Isaiah 6:3- The Lord of hosts and the One on the throne.
Isaiah 44:6- The Lord of hosts and the One true God.
The distinction between the Father and Son is also seen in Isaiah 44:6 and shows they are One God although distinct.
Jesus is distinct from the Father but is God Almighty. He is not less than the Father, and not a created being. He is the first and the last.
If ye believe not that I am He ye shall die in your sins (John 8:24, Exodus 3:14).
