God is one (Deut. 6:4), yet there are three divine persons (Matt. 28:19-20; Jn. 1:1). The reality of the Trinity is demonstrated clearly when Jesus was baptized (Matt. 3:13-17). Jesus was in the water, the Father spoke from Heaven, and the Spirit descended as a dove to rest on Jesus. There we do not see one being with three names. We see three distinct persons. Yet, these three are perfectly equal. The Holy Spirit is described as God (Acts 5:3, 4). The Son is described as God (Titus 2:13). This mysterious unity and distinctiveness is seen in John 1:1-3 where Jesus (the Word) is distinct from the Father (the Word was with God) and at the same time identical to the Father (the Word was God).
Why do we desire togetherness? Perhaps these desires spring from our being made in the image of God. We should understand that marriage is important because in some way it reflects the eternal unity and relationships enjoyed by the Trinity (Gen. 1:27) and the relationship of Christ and his church (Eph. 5:31-32). In marriage we see the expectation of love that is excellent and true. Why? Because that is what we see perfectly in the Trinity. In marriage, we also see voluntary submission between equals. Why? Because that is what we see perfectly modeled in the Father, Son, and Spirit.
A glance at our Triune God should move us to adoration and action. We are moved to adore their adoration of one another. That incredible love should be praised and we should strive to love as they do. We should also strive for that same sort of unity. That unity present among the Triune God should be reflected in our homes, congregations, and across the brotherhood of God’s people around the world.
