Luke 3

[21] Now when all the people were baptized, and when Jesus also had been baptized and was praying, the heavens were opened, [22] and the Holy Spirit descended on him in bodily form, like a dove; and a voice came from heaven, “You are my beloved Son; with you I am well pleased.” (Luke 3:21-22 ESV)

In the above verses out of Luke, we see a picture of the Trinity. First, Jesus, the Son is being baptized by John, second, God the Holy Spirit descended upon God the Son, and lastly, God the Father proclaimed that Jesus is his beloved Son whom he is well pleased. We also can observe that the Holy Spirit in this passage of scripture proceeds from the Father. Another more practical point is that God loves his son when he proclaims him as his beloved son. We too, are sons and daughters of the Father since we have a right with adoption. It says in Galatians 4 that, "[4] But when the fullness of time had come, God sent forth his Son, born of woman, born under the law, [5] to redeem those who were under the law, so that we might receive adoption as sons. [6] And because you are sons, God has sent the Spirit of his Son into our hearts, crying, “Abba! Father!” [7] So you are no longer a slave, but a son, and if a son, then an heir through God." (Galatians 4:4-7 ESV)
