Now when all the people were baptized, Jesus was also baptized, and while He was praying, heaven was opened, and the Holy Spirit descended upon Him in bodily form like a dove, and a voice came out of heaven, “You are My beloved Son, in You I am well-pleased.” Luke 3:21-22
One of the glorious moments in the gospels is when the Father, Son , and Holy Spirit all came together as one to begin the redemption of humanity. Here we see when Jesus was getting baptized, the Son coming out of the water, The Holy Spirit coming down and anointing him, and the Father giving his blessing upon this union
So you might ask , why did Jesus need to be baptized? Well first you have to consider Jesus needed to become human to die for our sins. Even though Jesus was fully God he was also fully man, a hard concept for us to grasp. However God cant die, so Jesus needed to be made human to be the atonement for our sins
Since Jesus is human, hes also vulnerable to temptations. But he is filled and anointed with the Holy Spirit, so the power of God is living inside of him.
“Go therefore and make disciples of all the nations, baptizing them in the name of the Father and the Son and the Holy Spirit, Matthew 28:19
Also Jesus would never ask us to do something he wouldn’t do. Jesus wouldn’t command us to get baptized if he wasn’t baptized either. Jesus was setting an example for us all, he never asked us to do anything that he hasn’t already done!
Notice Jesus says Baptize in the name of The Father, Son, and Holy Spirit! Our God is a Triune God Amen!
