The Trinity of God is the Father, the Son, and the Holy Spirit. They are all one God, but they exist in three separate persons. All three persons work together in perfect harmony and love. The Trinity is seen throughout the Bible, but especially in the Gospels. In the Gospel of Matthew, we see the Trinity at work in the baptism of Jesus. The Father speaks from heaven, the Holy Spirit descends on Jesus like a dove, and the Son is being baptized. This event shows us that all three persons of the Trinity are working together.
