The Trinity - A Lesson On Unity

Hello Everyone!

I came across an awesome sermon on the Biblical concept of the “Trinity” and really wanted to share it with you. Below is a condensed version! I hope you enjoy it as much as I did!

Blessings on your week!

Pastor Z.


Finally, brothers, good-by. Aim for perfection, listen to my appeal, be of one mind, live in peace. And the God of love and peace will be with you. Greet one another with a holy kiss. All the saints send their greetings. May the grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit be with you all.

2 Corinthians 13:11-14

When you read the Bible, you’ll find portions that clearly say God is one. In Deuteronomy 6 for example—“Hear, O Israel, the LORD our God, the LORD is one.” But as you continue to read, you’ll also find God described as three. At the very end of Matthew’s Gospel, Jesus describes God as “Father… Son… Holy Spirit...” (See Matthew 28:16-20)  Same thing in the passage you just read from 2 Corinthians 13. “May the grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit be with you all.” So which is it? Is God one or is God three?

It’s both. God is “Three-One” (Triune). God is “Tri-Unity” (Trinity). Make sense? Of course not! The concept of a triune God is completely illogical! Something cannot be “three” and yet also “one.” And yet, this is how God describes himself in the Bible. Father, Son and Holy Spirit—not three Gods—one God—equally powerful—equally eternal—the Triune God. This is how God reveals himself to us and has always been the belief of the Christian Church. It makes no sense. And that shouldn’t surprise us.

Imagine that you only existed in a two dimensional world. You knew about height and width but knew absolutely nothing of depth. Now imagine that someone who existed in three dimensions tried to explain to you a mysterious concept called a cube. It wouldn’t make any sense would it? Six square sides? What’s he talking about. He could even draw it out for you but since you only see in two dimensions you’d see nothing but a bunch of lines and squares on the page—you would not be able to perceive the cube.

Now what’s the point of this analogy? God’s like a cube? No. The point is this: Someone who exists in places where our thinking cannot possibly follow, beyond our dimensions of time and space, will not make sense to us. Our God existed before time and space and exists outside of those things now even as he enters into them to meet us. It is no wonder that we cannot grasp with our limited reason the very nature of our God. So instead of trying to understand the Trinity it is better to simply let God speak and tell our offended human reason to be quiet and listen to our God.

You see God reveals himself as he truly is—three in one—not to frustrate our logic but instead to bring us to marvel at the fact that our single perfect God—Father, Son, and Holy Spirit—who has spent eternity together—loving, honoring, and glorifying each other with a perfect unity—yes, our God who never needed us to make himself complete—Our God still chose to create this world—to create all of us—despite knowing what we would do—that we would despise our Creator—that we would reject his perfect will for us—that we would seek to be our own god—that we would ruin it all.

Despite all this God still made us—but more than that he chose to save us and to let us see it happen. And it happened in a way that is impossible for us to fully grasp. The Father sent the Son into the world because of his love. The Son demonstrated his grace to us as he went to the cross. There the Father would turn his back on the Son—his Son—with whom he had spent eternity. Yes the undividable and unbroken circle of the Trinity would be broken as our sins—our lies and lusts, our hatred and cruelty, our anger and rebellion and evil would be placed on the Son and would do what sin does—separate the offender from God! And so the Son who had never been parted from his Father was forsaken—the circle was broken—all so that you could be brought in!

You see, that is the true marvel of our Triune God. That he would allow such horror to befall him so that we would never have to face it—so that the perfect unity he had enjoyed among Father, Son, and Spirit would be something we could take part in. Just listen to what Jesus prayed to his Father the night before he died: I pray… that all of them may be one, Father, just as you are in me and I am in you. May they also be in us so that the world may believe that you have sent me. I have given them the glory that you gave me, that they may be one as we are one: I in them and you in me. May they be brought to complete unity to let the world know that you sent me and have loved them even as you have loved me (John 17:20-23).

Your God loves you so much that he sent his Son to pour out grace into your life. And he poured out his Spirit into your hearts so that through faith in Christ you would be brought into fellowship with God and with each other. Perfect peace. Perfect unity. All because of our perfect God. This is what became yours when you were baptized into the name of the Father and of the Son and of the Holy Spirit. This is what remains yours even now as you continue to be built up in the faith by the Spirit through his Word where he unites with you—through your Savior’s supper where he becomes one with you. The perfect unity and peace—the love and the fellowship that Father, Son, and Spirit have enjoyed with each other they share with you.

It is no wonder that Paul closes his letter to the Corinthians with the encouragements he does. After spending an entire letter addressing problems in their lives and in their congregation that threatened the peace and unity they have he tells them:  Be of one mind—live in peace—greet one another with a holy kiss—the saints send their greetings (2 Corinthians 13:11-13). When we have not only seen but have experienced the love and peace and unity of our God we cannot help but seek to model our lives after it—not in order to earn heaven, but rather to experience in this life a taste of that perfect unity and peace that waits for us in heaven—won for us and sealed to us by our Triune God!

Be of one mind my friends—live in peace—do not allow your sin or the sins of others to divide your marriages—your families—your friendships—instead greet each other with sincere hearts—forgiving hearts—remember that the same God who has forgiven all of your sins wants you to offer forgiveness to those who have wronged you—those who disobey you—those who have hurt you today or who will hurt you tomorrow. And as you aim for perfect obedience in this life always remember that your Savior’s perfect obedience is already yours. It covers you and empowers you to demonstrate love in all you say and do. As you go about your lives, you can trust that the God of love and peace—our Triune God—will go with you. May the grace of the Lord Jesus Christ, and the love of God, and the fellowship of the Holy Spirit be with you all!
