"Incarnate" means to be born in the flesh.
Yes it does....and John 1:14 says that it was “the Word” who “became flesh”, not Jehovah.
God’s law demanded
“an eye for an eye, a tooth for a tooth, and a life for a life”. The “last Adam” had to be the exact equivalent of the ‘first Adam’....a sinless life offered for the sinless life lost for the human race.
God’s “holy servant” was his “firstborn” son, (Acts 4:27) sent to earth to give his perfect life in sacrifice to buy back, (redeem) and to restore what Adam lost for his children.
I agree on this one. God, which is the Father did not come but sent His Son, Who is as the Father in what He said and did for the Father, for They are one in everything ("These Three are One" 1Jn 5:7).
I believe that is a mistranslation.
1 John 5:6-7 in the ASV reads....
“This is he that came by water and blood, even Jesus Christ; not with the water only, but with the water and with the blood. And it is the Spirit that beareth witness, because the Spirit is the truth.”
Translators can make their renderings imply whatever they want it to say, but there is no triune god mentioned by Jesus in any verse of the Bible.
God saw it was a greater sacrifice to send His Son than to come Himself.
And you ascertain that by what scripture?
In attempting to offer up his own son, Abraham showed that when God demanded that something be done, he would carry it out because of his trust in God’s will.
Paul wrote in Hebrews 11:17-19...
“By faith Abraham, when he was tested, as good as offered up Isaac—the man who had gladly received the promises attempted to offer up his only-begotten son— 18 although it had been said to him: “What will be called your offspring will be through Isaac.” 19 But he reasoned that God was able to raise him up even from the dead, and he did receive him from there in an illustrative way.”
We see here that Abraham’s trust was in the resurrection.....the illustration was pictorial of Jehovah’s willingness to sacrifice his own son, because the will of God required it. He knew that Isaac could be raised from the dead just as surely as God’s son was raised from the dead hundreds of years later.
An immortal God cannot die for a mortal man’s sin. Redemption required an exact amount to cancel the debt. Jesus was that mortal man, “sent” by his Father, but willing to take on the assignment, such is God’s love for mankind. (John 3:16)
