If God is this benevolent being that so many throughout the centuries have testified, I believe it would be impossible for Someone who is the epitome of Good not to have created humanity.
If we are created in the image of this Benevolent One, then it is because the type of life God enjoys must truly be quite a wonderful thing to experience. Someone truly good would not keep something to himself if it was truly marvelous. If there was enough for everybody, this Good God could not avoid creating others with the intellect and the spiritual capacity to grasp and enjoy this life as he does without denying himself.
Like those of us born to parents who truly wanted us, we were created by Love, out of Love, for Love, and to Love. While not meaning to wax poetic and end up sounding like some kind of Sunday sermon, what I mean is that if God is real and truly the type of Person that religions and the Bible claim, then the answer is simple. We were created because God wanted us.
Because God is Love, we were thus created by God, out of God, for God, and believe it or not “to” God. In other words our ultimate finality is linked to possessing life as God does and with God. God is our Origin and God is our Destination.
Granted, not everyone believes this and I am not saying that others somehow should. I definitely do not look down or pity or dislike the atheist for not believing this either, nor is this meant to be a challenge to them or others with a differing view. I am merely stating that it doesn’t make sense for God, being who he is supposed to be and how he is supposed to be not to create us. Otherwise God would be selfish because he did not want to share this thing called life. On the contrary God not only gives us life he shares with us the essence of his very own.
