2 Corinthians 13:11–14 God in Three Persons, Blessed Trinity

In the first half of the Church Year (Advent through Pentecost), we look at the life of Christ—his birth, ministry, death, resurrection, ascension, and the sending of the Holy Spirit. In the second half of the year, we look at the teachings of Christ. We begin by looking at one of the most mind-blowing truths: that God is triune. Already in the very first chapter of the Bible, we read, “Then God said, “Let us make mankind in our image…” (Genesis 1:26). Note the singular “God” and the plural “us.” Scripture teaches us that there is only one God but that he exists as three persons—Father, Son, and Holy Spirit. He is triune (three-in-one). This teaching is not some logical exercise or philosophical excursion. The doctrine of the Trinity is central to our salvation. The triune God is our Creator, Redeemer, and Sanctifier. Lose this doctrine, and as the Athanasian Creed says, you lose it all. A Jesus who is less than God is also less than a Savior. So often, when life gets hard, we get frustrated. We don’t understand how God is always working for our good. But the doctrine of the Trinity teaches us we cannot even comprehend God’s existence. How, then, could we ever comprehend all his workings? On this Holy Trinity Sunday, let it be enough to know that all three persons—Father, Son, and Spirit—love us with everlasting love.
