What do we know about God? To say “God” speaks of One Who is self-sufficient. A needy God is less
consistent than dry water or frozen fire! If God is God, then God does not need anything. One thing, that God is love. John, the “disciple whom Jesus loved,” who, we understand, clung the closest to Jesus during His earthly ministry and wrote not only the Gospel under his name, but three letters and the Revelation, is the one who passed that revelation on to us. Merciful, just, faithful, and true, all adjectives describing God’s nature, but to say, “God is love” not only describes Him, but gives us a one-word summary of His existence!
Since God is God, and so in need of nothing, and God is love, then the love that God is cannot be a need-love such as we experience as human beings, but a gift-love: A love that exists for the sake of the other, which delights in the good of the other, rather than in one’s own pleasure.
God has always been. Man is a newcomer. Unless we can prove an endless chain of other worlds, we have to deal with God being in a past eternity where we were not. God is love, and God is God. So while we can see that God is not lacking anything, that is, that He is not incomplete without the worship of a church, nation, etc., but also a gift-love must have a recipient. This rules out a lone, monistic God, or else He would be/have been frustrated in the very core of what He is.
If God is love, then either there is more than one Person involved in the Godhead, or a lone, and lonely, God was alone in the void-before-the-void for eternity before deciding to create a race to fill the void of His own lonely existence. Such a lonely, needy, individual would be more worthy of our pity than our worship! While speaking in far more general terms, the writer of Ecclesiastes speaks to this when He says, “Two are better than one, ..and a threefold cord is not quickly broken.”
A “company” of two speaks most commonly of a romantic setting, which at once is a picture of a need-love relationship, of one individual wanting to keep the other for themselves. Three, even in or own context, is more a group of each enjoying the others’ company, and enjoying the interaction between the other two. Also, any number greater would suggest parties, or factions, as the communication might be diverted to this or that part of the Whole, losing the whole concept of Unity. While it is fascinating to study the many ways the Trinity is implied, and, even spelled out, all through the Bible, simply to say, “God is love” is to say Trinity.
