Because the Father emptied Himself of some of the attributes of Deity when He descended to become the Son; and also stayed behind in eternity: therefore from the perspective of being in eternity God the Father was able to give unto Himself (in the Person of the Son) all power in heaven and on earth; which He had relinquished for the sake of becoming human.
In Revelation 1:6 it says,
Rev 1:6, And hath made us kings and priests unto God and his Father; to him be glory and dominion for ever and ever. Amen.
Apparently God has a Father.
Who is this God who has a Father?
Is it not Jesus Christ the Son of the living God?
And yes, there is also only one God (James 2:19). So, how is the Father not the one Lord of holy scripture when it is clear from these verses that the Father (God) is that one Lord? yet, the scripture also teaches that Jesus is the one Lord (1 Corinthians 8:6). And that no one can say that Jesus is the Lord except by the Spirit of truth (1 Corinthians 12:3 (kjv)).
Can you say that Jesus is the Lord in light of Matthew 11:25, Luke 10:21, and Ephesians 4:5? Read the verses before answering.
And yes, there is also only one God (James 2:19). So, how is the Father the one Lord of holy scripture when it is clear from these verses that the Father (God) is that one Lord? Because Jesus is the Lord. (Can you say that in light of the scriptures presented? If you can't, maybe you don't have the Spirit of truth (the Holy Ghost).)
The answer to the question of how, is that the Father descended to become a Man (He took on an added nature of human flesh) so that He might be able to die as a Man (see Revelation 2:8); since we know from other scripture (Isaiah 44:6) that Jehovah is the First and the Last.
His Spirit separated from His body (Luke 23:46) and this is the death that is being spoken of in Revelation 2:8.
Yes, God became a Man and died for you and me.
I know that this goes against everything that you believe as a Jehovah's Witness; but I believe that you must look at the testimony of the scriptures that have been presented.
The answer to the question of how, is that the Father descended to become a Man (He took on an added nature of human flesh); while staying behind in eternity in the Person of the Father so that Jesus (who is the Father) might operate as a human being and show us the way...for Jesus did in fact pray to the Father and this does not mean that He and the Father are not the same Spirit.
For, if you look at John 14:7-11 you will see that the Father was in Jesus and Jesus was in the Father; and that whoever saw Jesus was also looking at the Father. And in John 4:23-24 you will see that the Father is a Spirit. Therefore the Spirit who dwelt in Jesus Christ was in fact the Father (see also 2 Corinthians 5:19) and is the Father.
Therefore all you have yet to realize is that in what is called the hypostatic union, the human nature of Jesus is intertwined with His Divine nature so that in all of who Jesus is, He is God.
If you don't believe me, I would suggest looking up the scriptures that I have presented to you in the kjv...I trust that you accept its veracity as a Jehovah's Witness?
