"No he didn't! You cannot raise yourself from death, by definition of what death is!" -Jehovahite
"Therefore doth my Father love me, because I lay down my life, that I might take it again. No man taketh it from me, but I lay it down of myself. I have power to lay it down, and I have power to take it again." (John 10)
Jesus laid His eternal and everlasting life down on the cross willingly for our sins, and He took His eternal and everlasting life again in resurrection for our justification. (Rom 4)
Jesus was not immortal, therefore did not have eternal life, before his resurrection, otherwise he could not have died. This is why he was in such distress and sweat drops of blood in the garden of Gethsemane - because if he had sinned at all during his human life then his death would not pay the redemption price for mankind, and having sinned he too would have to pay the penalty for sin - eternal death.
John 10:17-18 (ESV):
17) For this reason the Father loves me, because I lay down my life that I may take it up again.
18) No one takes it from me, but I lay it down of my own accord. I have
authority to lay it down, and I have authority to take it up again. This charge I have received from my Father.”
Jesus is here saying that he has authority from God to lay down his life in sacrifice as the redemption price to redeem mankind - God anointed him for that purpose (Messiah means anointed). Nobody else has been given authority to do that. God (our Father, Yahweh) told Jesus to do so, and promised that He would raise Jesus to life again.
Regarding Romans 4:
22) And therefore it was imputed to him [Abraham] for righteousness.
23) Now it was not written for his sake alone, that it was imputed to him;
24) But for us also, to whom it shall be imputed, if we believe on him that raised up Jesus our Lord from the dead;
25) Who was delivered for our offences, and was raised again for our justification.
It says that righteousness is imputed to us if we believe in God (Yahweh, our Father) who raised Jesus from death. I do believe in God, whereas you have a confused belief of who God and God's son are; you believe they're both God, along with another unnamed being.
Jehovahites are deniers of the Son as God, and so also deny the Father as God (1 John 2), ...
I have have always claimed that Jesus is the son of God, and that he is a mighty god, second only to God himself, to whom God has given all power and authority in heaven and on earth (Matthew 28:18). I have never denied that the Father is God - in fact I've been saying all along that Yahweh, our Father and Jesus' Father, is the only true almighty God, and as Jesus said, Yahweh is greater than Jesus.
As for 1 John 2 (WEB):
20) You have an anointing from the Holy One, and you all have knowledge.
Note it says
One not Three.
21) I have not written to you because you don’t know the truth, but because you know it, and because no lie is of the truth.
22) Who is the liar but he who denies that Jesus is the Christ? This is the Antichrist, he who denies the Father and the Son.
I have never denied that Jesus is the Messiah. I have confirmed what Jesus claimed, that he is God's son.
23) Whoever denies the Son, the same doesn’t have the Father. He who confesses the Son has the Father also.
I confess that Jesus is the son of God, the Messiah. Just like Peter did (Matthew 16:16-17):
16) Simon Peter answered, “You are the Christ, the Son of the living God.”
17) Jesus answered him, “Blessed are you, Simon Bar Jonah, for flesh and blood has not revealed this to you, but my Father who is in heaven.
