First I have to commend you for your logic on many levels. It is rare that I find some one willing to reason this out and at the start has so many things right! You already see that Jesus is not God.
That Jesus is his own son. You already see that we need to work out our salvation individually. Now lets take a closer look and see if we can understand why the way Jehovah did this was the absolute best way.
HOW it all BEGAN Sorry if I have to take you so far back but lets go back to where it all began please, To Genesis Chapter 3. What happened in the Garden with the first humans holds a lot of details we must understand. This was no haphazard thing that Satan did.
It was well planned. After all he knew who he was going to pit himself against. In such a crafty way Satan Challenged God's Exclusive Right to rule the universe.
Come on does he have to be the only one in charge? No one really can follow his strict rules. Besides we are better off doing things our own way.
Surly some one can do it better, or at least make it on their own without him. God just wants to keep us under his thumb. He does not really care about us.
Additionally Satan asserted that not one could no one obey Jehovah but no one would want to. No one would do so out of love. This is high lighted even more so in the first 2 chapters of Job.
There we see a heavenly court session taking place and Satan hurling his accusations against anyone who serves Jehovah and also against Jehovah himself. These are the simplified way Satan raised issues about God's Sovereignty. All to under mine it.
THE MOSAIC LAW! Most people do not understand the harshness of the Mosaic law. (Galatians 3:19 Romans 5:12) Well the point was to show how imperfect and pitiful we are now that we have sin to deal with.
Not one single individual could perform the law completely and gain life. Now Jehovah did not like animal sacrifices. But a point had to be made.
That there was only one way to gain salvation. That was eye for eye tooth for tooth soul for soul. Animals where not equal to man.
And those who sacrificed where well aware of this. Something better was needed to pay the price. But what actually was the price?
The PRICE Each individual is not completely accountable for the sins he commits because we are tormented by our sinful nature. - Romans 7:24 The thing that was lost was a perfect father ADAM! The first man Adam lost perfection.
There was no one that was perfect who could replace him. We needed a perfect man to replace a perfect man. Where JESUS comes in.
Jesus, who was God's first borne and who witnessed all these things, was willing to come down from heaven and prove each and every issue that Satan raised to be a lie. He represented not only God but also man.
Simple actually, you make it more complicated than it is. Jesus took on the sins of the world, on Him alone He took what you and I and the rest of the world deserve. You see on earth we have a choice to choose good or evil.
In heaven there is only good the opposite (hell) there is only evil only on earth the two are together with our free will able to choose. So when you die without the cleansing of our soul by the blood of a sinless sacrifice, (Jesus) we cannot enter heaven, you cannot have both in heaven because God is only good. And you said why didn't he come and handle it, He did all you need to do is believe and stop doubting.
God does not grade salvation on the curve you must be perfect as He is perfect to enter heaven. You can be cleansed by Christ blood and be perfect and acceptable to God. There is no price to pay, He already paid for you, you only need trust in Him.
Even if you were to replace a part on you car. Would you just want some marginal part or the best. Of course you want the best, should God receive less?
I don't understand the whole part you said about helping your fellow man, of course you should, All these things are things Christ would do and we should strive to be like and trust in Him. And your whole problem about not understanding or thinking it should have been done another way, well you are not God and have very little understanding compared to Him so TRUST and stop trying to figure it all out on your own.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
