Do you know why God decided to create angels and then humans? And then go to all the bother of getting all these events here on Earth and in Heaven to take place?
What is His main drive to do all this? And what is His final expected outcome? And for what reason?
Looking from our position right now we see what’s coming and what’s going to happen, but I’m wondering what is God’s main underlying reason for getting all this to happen?
He must have some outstandingly huge purpose for us in order to put all these events into action. Which brings me to the question why does He require us when he can do everything Himself?
What is our ultimate destiny as His Church?
A whole bunch of people have tried to answer these questions. The best one I’ve found for your first one comes from one of Hal Lindsey’s books, I think it was “Satan’s Alive and Well on Planet Earth”. In it Hal speculated that when Satan was judged, he complained to God, “You’re not just and You have no love.” So God set about to demonstrate perfect justice and perfect love.
First He created man, a being vastly inferior to the angels but sharing with them eternal existence, intellect, and agency. Then He gave man a set of righteous laws to live by. These laws reflected His standards for behavior required to dwell in His presence. And He determined that anyone found guilty of breaking even one of these laws, even if it was only in his mind, would be subject to eternal punishment. There would be no exceptions, no exemptions, no favoritism, no appeal. Keep the law and live, break the law and die. Perfect justice.
To demonstrate perfect love, He became a man Himself, and lived a life in full compliance with His law, the only man ever to do so. Then He agreed to assume full responsibility for all of mankind’s violations of His law. He would die in our place. And to everyone who agreed to this substitution, He would grant eternal life with Him as His children, considering us totally innocent of all our violations. He would exclude none from asking and would require no further action beyond acceptance of His death in our place. Every one who asked would receive a full pardon and be welcomed into His family. Perfect love.
Though the preceding is informed speculation, the following is not. His purpose in doing this is two fold:
1) so that now, through the church, the manifold wisdom of God should be made known to the rulers and authorities in the heavenly realms, according to his eternal purpose which he accomplished in Christ Jesus our Lord. (Ephes. 3:10-11) and
2) so that in the ages yet to come He might demonstrate the incomparable riches of His grace expressed in his kindness to us in Christ Jesus (Ephes. 2:7)
As you can see, it’s the Church’s destiny to be the agency through which He refutes Satan’s accusations, and as our reward, to receive all that Satan lost in his attempt “to become like the Most High.” He had been the most powerful and influential of all created beings, guarding the Throne of God, and given the honor of leading the universe in singing His praises. Now that position belongs to us, but rather than merely guarding the Throne, we’ll be sitting on it.
