Readings: Isaiah 6:1–7 | Romans 11:33–36 | John 3:1–17
Text: John 3:1-15 (Isaiah 6:1-7, Romans 11:33-36)
Trinity Sunday is a feast day to remember that God is transcendent, and in many ways for us, unknowable. He’s greater than us, and not just in the way that a king is greater than his servant, because He is “ruler of kings on earth” (Rev. 1:5). He’s stronger than us, and not just in the way that a body builder is stronger than a computer geek, for He is rightly called Pantokrator or All-Powerful, Almighty. He is infinitely stronger than any human being—“Shall we provoke the Lord to jealousy? Are we stronger than He?” He is also beyond all human understanding. His thoughts are not our thoughts; nor are his ways our ways. No matter how we may apply our reason to Him, He is beyond us. That’s why every analogy for the Trinity—apples, sun, or clover—ultimately cannot encompass the mystery of the Triune God—Father, Son, and Holy Spirit.
But in our egalitarian society, we have a hard time comprehending the greatness and otherness of God. We’re told from childhood that, deep down, everyone is the same. We all have the same aspirations and fears. And we see this in practice when presidents invite common citizens for a beer, celebrities are seen at Wal-Mart, and the pope chooses to go for a walk rather than ride in the bulletproof motorcade. With so much equality among men, it’s hard for us to remember that God is always above us. The singer Joan Osborne wrote the anthem for this sentiment when she sang decades ago, “What if God was one of us?”
And yet God is far from unknown to us. How can this be? We know Him from Holy Scripture. He calls Himself our heavenly Father. Now with our earthly fathers, when we were kids, we thought of our dads as invincible and infallible. But as we grew to be an adult and especially when we had kids of our own, we saw that our fathers were people just like us. Not so with God the Father. It’s more than an flawed analogy; rather, God is the originator of all fatherhood, but He will always be greater than us. He is truly the One “from whom all fatherhood in heaven and on earth is named.” (Eph. 3:15)
But in an attempt to deal with our fear of God, we like to convince ourselves that God isn’t as scary as He was in the Old Testament. Remember Uzzah, whom the Lord put to death, while the Ark of the Covenant was being carried into Jerusalem:
“Uzzah put out his hand to the ark of God and took hold of it, for the oxen stumbled. 7 And the anger of the Lord was kindled against Uzzah, and God struck him down there because of his error, and he died there beside the ark of God.”
The God we have come to know through Jesus Christ is the same holy God whom we worship today. But our fleshly security is uncomfortable with the truth that “our God is a consuming fire.” We prefer a Heavenly Pushover, who is impressed with our clever decisions and cheers us on from the sidelines.
This Sunday is also a time to consider what the Holy, Transcendent God does. Many man-made religions recognize that God is “Immortal, Invisible,” and “Only Wise” But if that’s all there is, then we’re toast. Woe to us! For we are lost; for we are people of unclean lips, and we dwell in the midst of a people of unclean lips. God has more to show us than His omnipotence.
The Gospel from John 3:
3 Now there was a man of the Pharisees named Nicodemus, a ruler of the Jews. 2 This man came to Jesus by night and said to him, “Rabbi, we know that you are a teacher come from God, for no one can do these signs that you do unless God is with him.” 3 Jesus answered him, “Truly, truly, I say to you, unless one is born again he cannot see the kingdom of God.” 4 Nicodemus said to him, “How can a man be born when he is old? Can he enter a second time into his mother’s womb and be born?” 5 Jesus answered, “Truly, truly, I say to you, unless one is born of water and the Spirit, he cannot enter the kingdom of God.
No matter how we peer into heaven, we are incapable of grasp God—“no one knows the Son except the Father, and no one knows the Father except the Son and anyone to whom the Son chooses to reveal him.” (Matt. 11:27) In fact, what Jesus says here is that that’s the wrong direction. Stop trying to ascend to get a glimpse into the divine.
Instead, God makes Himself known to us. Even though “the eye of sinful man His glory may not see,” the Holy One has come down from heaven. As John says in His prologue, “the Word became flesh and dwelt among us, and we have seen His glory, glory as of the only-begotten Son from the Father.” We aren’t the ones who ascended to know God, but as Jesus says, “No one has ascended into heaven except He who descended from heaven, the Son of Man.” So, right after explaining that no one can know Him except by His choice, He invites you, “Come to me…and I will give you rest.” (Matt. 11:28)
All too often, we approach God with our own ideas—ideas about who He is, how He works, and what He should do for us. But that all gets turned around: “You must be born again! Flesh gives birth to flesh, and the Spirit gives birth to spirit.” You must cast away your fleshly thinking about God, and receive Him in humility. “Be born again by water and the Spirit” and you will not only see God, but you will also be brought into His Kingdom!
The Son of God—“true God, begotten of His Father from eternity, and also true Man, born of the virgin Mary” (Small Catechism, 2nd Article)—has come down from heaven, but He didn’t come down just to give us supernal thoughts about the divine. The Lord whose Name is majestic in all the earth, came down to earth to be lifted up from it. Jesus explains, “as Moses lifted up the serpent in the wilderness, so must the Son of Man be lifted up, 15 that whoever believes in him may have eternal life.” This is what He came down from heaven for: to be lifted up in weakness, the humility of death. The King of Heaven Himself was lifted up on the cross to save us lowly, sinful creatures.
In our experience, those who are great don’t help the weak. When we, who have comfortable homes and stable jobs, see someone who is homeless and unemployed, we turn our eyes away. Some of their misfortune might rub off on us! It might cause us to have to sacrifice some of our comfort to aid them in their suffering. But praise the Lord, who is not miserly and selfish like we have been! In 2 Corinthians 5, St. Paul writes, “For our sake He was made sin who knew no sin, so that in Him we might become the righteousness of God.” The Holy God in human flesh became unholy and a sinner. It was pure gift to us, who are unholy from our very hearts!
Thinking of the Old Testament lesson, how was it that Isaiah could stand in the presence of God? “6 Then one of the seraphim flew to me, having in his hand a burning coal that he had taken with tongs from the altar. 7 And he touched my mouth and said: ‘Behold, this has touched your lips; your guilt is taken away, and your sin atoned for.’” God’s holiness would have consumed Isaiah, yet with what came from the altar, his sin was atoned for.
Now, where did those coals on the altar come from? Were they offered by us? If this had been the altar of the Levitical priests, it would have been the remnant of the sin offering. No, those coals were of a sin offering which the Holy One Himself made on our behalf. “So must the Son of Man be lifted up.” And through that sacrifice alone can we stand before the face of the thrice-holy God.
The Transcendent One has come down so that we might be raised up. He was raised up on the cross, “that whoever believes in Him may have eternal life.” We like to boast about ourselves and our lives. When we have a bad day, we feel better when we see others having a worse time. But in truth, we are poor and needy, lowly, and afflicted. Our transgressions and the evils that happen to us bring us very low, sometimes even to the point of death. But He who is Almighty is also merciful and compassionate toward us. We have a great High Priest who is like us un every way, except without sin, one who invites us to draw near with boldness to the throne of grace (Hebrews 2, 4). Thus, He comes to us, like the disciples on the mount of Transfiguration, touches us, and bids us to rise and have no fear. “Your guilt is taken away; your sin atoned for.” (Isa. 6:7)
God has taken our humanity into Himself so that we would truly be raised up. Jesus takes away the shame that covers us. He heals our bodies and souls by His own wounds. When death looms over us, we have eternal life though Him. We live confident of all of this, hoping for the End of all things, when He will exalt us completely.
In that Day, we will still be creatures. But we will be restored from the pitiful state we live in now. The perishable will be raised imperishable, and we who are mortal will put on immortality. Our longing to be free of evil will at last be satisfied and all the faithful whom we have lost will be restored to us. God is unknowable by human ability. But God’s light shined in our darkness. The Triune God made Himself known in the womb of the Virgin, in His human life from infancy to adulthood, in His passion and death, and gloriously in His resurrection and ascension. He bore our death so that we might live before God in righteousness and purity forever. “What if God was one of us?” The glorious Son of God has made the Trinity known, in a way that we are left to cry out, “How unsearchable are his judgments and how inscrutable his ways!” (Rom. 11:22) The Lord God Jesus became one with us, and He has given us a share of His divine life. So, we do indeed praise God the Father, God the Son, and God the Holy Spirit, ever one God, world without end. Amen.
