16 When He had been baptized, Jesus came up immediately from the water; and behold, the heavens were opened to Him, and He[
a] saw the Spirit of God descending like a dove and alighting upon Him. 17 And suddenly a voice
came from heaven, saying, “This is My beloved Son, in whom I am well pleased.”
Matthew 3:16&17
This an appearance of all three. Father(speaking) Jesus(being baptized) Holy Spirit (descending)
And the Holy Spirit descended in bodily form like a dove upon Him, and a voice came from heaven which said, “You are My beloved Son; in You I am well pleased.”
Luke 3:22
Notice the Spirit came in bodily form?
And John bore witness, saying, “I saw the Spirit descending from heaven like a dove, and He remained upon Him. 33 I did not know Him, but He who sent me to baptize with water said to me, ‘Upon whom you see the Spirit descending, and remaining on Him, this is He who baptizes with the Holy Spirit.’
John 1:32 & 33
And being assembled together with
them, He commanded them not to depart from Jerusalem, but to wait for the Promise of the Father, “which,”
He said, “you have heard from Me; 5 for John truly baptized with water, but you shall be baptized with the Holy Spirit not many days from now.” 6 Therefore, when they had come together, they asked Him, saying, “Lord, will You at this time restore the kingdom to Israel?” 7 And He said to them, “It is not for you to know times or seasons which the Father has put in His own authority. 8 But you shall receive power when the Holy Spirit has come upon you; and you shall be witnesses to Me[
a] in Jerusalem, and in all Judea and Samaria, and to the end of the earth.”
Acts 1:4-8
Do you reckon that the God that spoke the world into existence is not completely understood? I mean.....If He can speak the world into existence, is it possible that He'll have concepts that we don't understand?
