The Most Holy Trinity is often referred to as a mystery of faith. But is a mystery something we cannot understand? Not at all, we can understand the mystery of the Trinity to the extent that God has revealed it to us.
So what has God revealed to us about Himself?
We have always known the answer. As we are created in His image, we look at ourselves to gain an understanding of God. What we find is that man is incomplete when he is alone. Our need for relationships is so strong we will even endure flawed and broken ones because the alternative is too hard for us to bear. But any relationship that is not based in love, a mutual self-giving, is doomed to fail. Love is our most fundamental characteristic.
And so we can say that God is love, and that makes Christianity different from every other religion in the world. Almost every other religion starts with man’s search for God. But Christianity is the fulfillment of God’s search for man. Out of His love for us God came to rescue us from our fallen existence. In doing so He has revealed to us who He is and what He is like. And His most fundamental characteristic is love.
It is by far the most popular verse in the bible.
“God so loved the world that he gave his only Son, so that everyone who believes in him might not perish but might have eternal life” (John 3:16)
