Where's the Justice?

[Undeceived]

This is love: not that we loved God, but that he loved us and sent his Son as an atoning sacrifice for our sins.

You have not answered my question. Why should we love god and why should this god love us?

There is no imperative 'should'. God chose to love us; we know he loves us because he sacrificed himself for us. We can choose to love him back, or not.

Dear friends, since God so loved us, we also ought to love one another. No one has ever seen God; but if we love one another, God lives in us and his love is made complete in us."

Why to any of this?

"If we love one another, God lives in us and his love is made complete in us." We want God to live in us because we feel fulfilled inside. Without him we are always searching and anxious, and experience grief. I suppose we might love for a feeling. Feelings are why we do most things--we want pleasure or an escape from hardship. That is our selfish motivation, anyway. Once I recognized what God did for me, he put a desire in my heart to love him back apart from a reward. He lives inside me. That's the whole point. If someone loves you, why do you love them back? Is it because you will get something? If not, why? Answer that and you will have answered your own question.

God does not need us to do anything for Him because He is all powerful.

Contradiction. You said this thing wants our devotion. Why does it need our love?

He doesn't need anything. He loves us like a father loves a child. Like a father, he would melt with happiness if we loved him back. He does not need anything from us, his creation, to survive. He simply wants the best for us. And he knows the best means having a strong relationship with him. Imagine your son is getting caught up with gangs and drugs. Do you 'need' him to set his life straight? Or are you just frustrated because he can't see how much better his life would be without the gangs and drugs?

With Jesus, our death will no longer be eternal.

I find the fact of eternal oblivion to be wonderful. Its true peace and everlasting freedom from the chains of reality and the burden of identity. Its greater than your silly god concept.

Which would you rather do--have an eternal feast of all your favorite foods or sleep eternally at the table? The choice is not difficult to make--all it requires is one thought. Of course, I believe the sleep (oblivion) option does not exist. Rather, there is a pit below the table where you will be eternally hungry.
(All a metaphor. Not literal as far as I know.)
