Who is the `me` that is speaking? -> It is preincarnate Christ Jesus
The LordJesusChrist is preeminent and He must be preeminent in us in order for us to be accepted by Him.
Not understanding that Jesus is the `God` who speaks throughout the Bible is the cause of much confusion and weakness in the BodyOfChrist.
This verse is echoed in the NewTestament verses: Rom 14:11 Mat 28:18 Col 1:16.
The mystery of God is revealed in John 1:1.
John 1:1 explains that the eternal, omniscient, omnipotent, omnipresent God is Soul and Spirit. It goes on to explain that the SoulOfGod was made flesh and dwelt among us.
We know that the HolySpiritFather filled Christ Jesus to the extent that He said: ^I and my Father are One^ Joh 10:30.
Jesus is SpiritSoulAndBody just as we are 1Th 5:23 who were created in His image Gen 1:27.
Jesus is the SpiritSoulAndBody of God.
Give all praise, glory and honor unto Christ Jesus as the One and Only TrueAndLivingGod.
