This would take pages so I will spare you and keep it as short as I can.

God is holy. He can not even look upon sin. He didn’t create it. He can't have anything to do with it. Angels had a choice at some time in Biblical history to choose between God and Lucifer. The choice that they made gave us holy and unholyangels (demons). By his own choice Lucifer became Satan.

Now God doesn’t have a choice to sin or not to sin but angels did. If they had the exactly same nature as God, they would be God and there would be no choice for them. When Adam and Eve disobeyed God by eating from the Tree of Knowledge ofGood and Evil, they brought spiritual death into the world. Since that time every person has been born with a sinful nature, except Jesus. Now Adam was created innocent but was not created righteous. Righteousness is innocence that has been kept is the presence of temptation. If we come through temptations we will be better people with stronger characters. Man was created a responsible being and part of that responsibility was to glorify and obey God, which Adam and Eve did not. Even if a person could live their life without sinning their sinful nature is still unacceptable to God.

The sacrifice God required was a sinless one. Only that would be acceptable to Him. I guess God thought the best way to communicate with us was to become one of us. He wanted all of us to be brought back into His Presence.

FOR AN EXAMPLE - ONLY:

LETS SAY THAT YOU WERE HOLIDAYING OUT IN THE OUT BACK & you noticed an   ANT NEST IN THE DRY RIVER BED.

You were somewhat concerned as THE FORECAST IS FOR RAIN & the river bed would be over run by water once again.  This would mean the DEATH to the Ant nest.

AS A CARING PERSON YOU WANT TO SAVE THE ANTS FROM COMPLETE DESTRUCTION SO YOU START TO DROP SOME BREAD CRUMBS FOR ANTS TO FOLLOW YOU OUT OF THEIR HOMES  to a new safe place.

IT SEEMS TO BE WORKING AS THE ANTS ARE FOLLOWING YOUR FOOD TRAIL & YOU ARE VERY PLEASED WITH YOUR SELF.

FEW HOURS LATER YOU GO BACK TO SEE WHERE DID THE ANTS RE-ESTABLISH. TO YOUR AMAZEMENT THEY RETURNED BACK TO THE ORIGINAL NEST.

YOU REALIZE THAT YOU ARE RUNNING OUT OF TIME - SO YOU TRY TO USE YOUR HANDS TO MOVE THE NEST - BUT TO YOUR AMAZEMENT  THE ANTS ARE BITING YOU SO MUCH THAT YOU HAVE TO ABANDON THEM THERE.

WHY DID THEY RETURN TO THE ORIGINAL NEST AFTER YOU GAVE THEM FOOD TO HELP THEM ESCAPE THE DESTRUCTION THAT  WAS COMING UPON THEM??

WHY DID THEY BITE YOU - SO THAT YOU HAD TO LEAVE THEM THERE?

AFTER ALL - YOU WERE TRYING TO SAVE THEM FROM DESTRUCTION - YET THEY DIDN'T LISTEN TO YOU.

THE Answer is - that you are of a different kind. For you to be able to COMMUNICATE WITH THEM, YOU HAD TO BECAME ONE OF THE SAME KIND - THAT IS - YOU HAD TO BECAME AN ANT & THEN GO IN TO THE ANT NEST & TELL THEM THAT THERE WILL BE A DELUGE OF WATER UPON THEM SOON & THAT THEY BETTER LEAVE THEIR COZY HOME & Leave if they wanted to save their lives.

Same principle applied to GOD - Even though God tried ever so hard to WARN the ISRAELITES TO HEED HIS LAWS & FOLLOW HIM, THEY CONTINUALLY REJECTED HIM AS THEY COULDN'T SEE HIM & THEY COULDN'T COMMUNICATE WITH HIM.

SO GOD BECAME ONE OF US.

The Holy Spirit impregnated Mary and 9 months later Jesus Christ was born. Here we have the example of God plus a human equals God (who is sinless), in human form. From memory where the mothers blood feeds the baby in the womb it does not touch it. The only blood Jesus Christ could have had is God’s, or perhaps a better way of saying it is ‘sinless blood’.  Blood without the ramifications of spiritual death.  Only one with the nature of God would be able to fulfil this. Jesus was the one who could not sin. Only an innocent sacrifice was acceptable to God. Notice how God paid the price for us and didn’t expect us to do it ourselves.

Even though god was manifested in HUMAN Flesh man continued to be disloyal & they had Him Crucified on the Cross.

However = He didn't leave us ALONE - He left His Holy Spirit to guide us in to all the Truth & so that His Spirit communicates with our SPIRIT - CRYING OUT ABBA FATHER ON OUR BEHALF. Galatians 4: 5=7 & Romans 8: 1-16.

when we became Born Again Christians - Life is ever so much easier as We are Led By God & our Spiritual Salvation is assured.

 See our page onBEING BORN AGAIN.

Angels were not able to offer us this salvation as they DIDN'T POSSES THE SINLESS NATURE. Just as Lucifer wanted to be equal in Power to God & he chose to sin as did his angles - It reacquired God Himself to come down from his heavenly Kingdom & offer us eternal salvation.
