When I begin with the premise, "God is love", then I conclude this is the one way that He will achieve His intent. That He have an eternal family of those who in reality love Him. The Only real love is voluntary, and the only voluntary love that can come from eternal creations is that which is chosen. This requires opportunity to choose, and means wrong choices have real consequences.Not a lot. As I analyze the Crucifixion, I ask whether it was necessary for forgiveness of our sins. If it wasn't, and was just God's chosen means from among other alternative ways to forgive our sins, why would He choose this one? And if it WAS the only available alternative, what does that say about Him and His power to forgive?
Man is not intrinsically good, as God is, and therefore man is not stable, and is subject to fall. Jesus is our rescue, in having made the choice in a fallen humanity, we are then moved to a new humanity, made alive by Jesus Christ Himself, Who IS intrinsically good, and therefore, we will be alive with Him forever.
The necessity for Jesus' death and resurrection is that in sharing this, we are freed from the law of sin and death. The soul that sins dies. We've died in Christ, a "survivable death".
Much love!
