John 17:1–6 (NKJV)

Jesus spoke these words, lifted up His eyes to heaven, and said: “Father, the hour has come. Glorify Your Son, that Your Son also may glorify You, as You have given Him authority over all flesh, that He should give eternal life to as many as You have given Him. And this is eternal life, that they may know You, the only true God, and Jesus Christ whom You have sent. I have glorified You on the earth. I have finished the work which You have given Me to do. And now, O Father, glorify Me together with Yourself, with the glory which I had with You before the world was. “I have manifested Your name to the men whom You have given Me out of the world. They were Yours, You gave them to Me, and they have kept Your word.

Today is Trinity Sunday, the Sunday we explicitly remind one another that the God we worship is Triune – three Persons in one God, Father, Son, and Holy Spirit. Later in worship we will recite the Athanasian Creed, one creedal attempt to articulate our Triune faith.

Jesus’ prayer in John 17 reveals the relationship among the Persons of the Trinity that has existed for all eternity. For all eternity, the Father and Son have loved one another with such a deep bond that that love is Himself a Person, the third Person of the Trinity, the Holy Spirit. In their bond of love, Father and Son share glory with one another. Jesus prays, And now, O Father, glorify Me together with Yourself, with the glory which I had with You before the world was. Jesus asks the Father – the Father who declared through Isaiah, “My glory I will not give to another…” – Jesus says to this Father, glorify Me together with Yourself… And note that it is a particular type of glory, the glory which I had with You before the world was. Prior to His incarnation, Jesus existed in the form of God and, though His deity was veiled during His time on earth, now that He has risen from the dead and ascended into heaven, that glory has been restored to Him. Jesus was and is God Himself in human flesh. The Father, Son, and Spirit share glory.

Second, Jesus reveals that in eternity past, before the world was, when the Father and Son shared glory, they communed with one another, they lived in a relationship of love with one another. Jesus alludes to this eternal fellowship a couple times. He says, I have glorified you on the earth. I have finished the work which You have given Me to do. In eternity past, before the world was, the Father gave Jesus a task to accomplish, a work to perform. Not only did the Father give the Son a task to do, He also gave Him a people to call His own. Jesus prays, I have manifested Your name to the men whom You have given Me out of the world. They were Yours, You gave them to Me… So when did the Father give these people to the Son? Before the world was. As Paul writes, the Father “chose us in Christ before the foundation of the world” (Eph 1:4).

This interaction between the Persons of the Godhead prior to the foundation of the world is sometimes called the Covenant of Redemption or the pactum salutis. God the Father, Son, and Holy Spirit have dwelt in covenantal life for all eternity. As we consider this Covenant of Redemption, that before the foundation of the world God thought of us, loved us, and gave us to be Christ’s own people – apart from any merit of our own; indeed despite the demerit which He knew we would deserve – ought we not to be humbled and awed that the Creator of all took notice of us? As Paul writes, “But we are bound to give thanks to God always for you, brethren beloved by the Lord, because God from the beginning chose you for salvation through sanctification by the Spirit and belief in the truth, to which He called you by our gospel, for the obtaining of the glory of our Lord Jesus Christ” (2 Thes 2:13-14).

And so reminded of the great love which the Triune God, Father, Son, and Holy Spirit has bestowed upon us, and that He loved us before the foundation of the world and loves us despite our unloveliness, let us confess that we are unworthy His love. And as you are able, let us kneel as we confess our sins together. We will have a time of silent confession followed by the corporate confession found in your bulletin.
