Firstborn from the dead, Born again as a spirit
The Word became flesh
None of us could pay the 'ransom' placed on mankind, because of the act of a perfect man Adam, who disobeyed. Remember, the promised penalty was death, and so Adam and Eve were placed outside of Jehovah's protective care. In time they grew old and died [subsequent imperfection], a trait that was passed on to all their progeny [all of us].
So then Adamic death ruled from Adam to the Mosaic laws. Since the Mosaic laws, transgression ruled [since the Law is perfect, but, we are not, and if we break one we break all].
God's Word was sent [of course He willingly consented to being sent, but it was Jehovah's WILL, or plan of reconciliation that facilitated this act]. John 8:42, John 6:38.
John 8:42 (Worldwide English (New Testament))
42Jesus said to them, `If God were your Father you would love me, because I have come from God. I did not come by my own power. God sent me.
John 6:38 (Worldwide English (New Testament))
38I did not come down from heaven to do what I myself want to do. I came to do what the one who sent me wants me to do.
So, it needed another perfect male [remember the man, is the head of the woman 1 Cor. 11:3], to equal the value of what was lost when Adam sinned.
The Word as flesh was a perfect man, being conceived by the lifeforce of the Word being transferred to the womb of a Jewish virgin, by the power of Jehovah's holy spirit.
But, Jehovah's Son, as a perfect man, was also able to successfully answer ALL of the false charges made by the Adversary or Satan [Proverbs 2:4, 5].
Jehovah's Son, Jesus the Christ, by His obedience to death, accomplished all that was necessary for Jehovah to reconcile obedient members of mankind.
1. Christ's sacrificial death provided a propitiatory for release from Adamic death. One no longer had to die just because of the inheritance from Adam.
2. As Mediator of the New Covenant [Jeremiah 31:31 to 34, Hebrews 8: 6-13; 10: 14 - 36], forgiveness of subsequent unintentional sins
became a reality, and the sealing of a New Nation of kings and priests [Re 20:6], was accomplished.
3. As High Priest [Psalm 110:4, Hebrews 6:20, 8:1, 2], Christ can plead to Jehovah on our behalf.
4. Being raised as a spirit Being, Christ was the first of New Jerusalem, Jehovah's future Administration of kings and priests from earth, a heavenly organization, of born again as spirit sons of Jehovah [Romans 1:3, 4; Re 20:6; 1 Cor 15:45].
No human born in sin, could pay this ransom, so none of us can boast. But after placing our faith in this provision [John 3:16], we have to act accordingly, because faith is revealed by appropriate works [James 2:17; Romans 10:9, 10].
