It came to pass in those days that Jesus came from Nazareth of Galilee and was baptized by John in the Jordan. And immediately, coming up from the water, He saw the heavens parting and the Spirit descending upon Him like a dove. Then a voice came from heaven, “You are My beloved Son, in whom I am well pleased.” Immediately the Spirit drove Him into the wilderness. And He was there in the wilderness forty days, tempted by Satan, and was with the wild beasts; and the angels ministered to Him.

Mark 1:9-13 (NKJV)

 

The baptism of Jesus is such a significant event that all three Persons of the Trinity are present. Even though Jesus is God, both the Father and the Holy Spirit continue to be the ultimate source of His calling and power during His earthly ministry. The Father affirms Jesus’ mission by referring to Him as "the Beloved Son", and the Holy Spirit anoints Jesus to fulfil His ministry to us.

Without the Trinity, the doctrine of the atonement becomes unintelligible and useless. It will appear as if Jesus was saving us from God rather than leading us to Him. We will somehow believe that the finished work of the Cross is about appeasing an angry God rather than revealing a loving Father.

The perfect harmony and love within the Trinity lead to an unparalleled form of self-giving. Each person of the Trinity works together for our salvation by accomplishing everything necessary to redeem us from sin and save us for eternity. We can see this from the incarnation to the baptism, crucifixion, and resurrection of Jesus.

According to Apostle Paul, God was in Christ reconciling the world to Himself, by not counting people's sins against them (2 Corinthians 5:19). So how should we respond to having so great a salvation? We can follow the example of Jesus to submit God’s way of life working in and through us.
