The trinity which is the Father, the son and the Holy spirit shows the power.
In Matthew 3 vs 16 made us understand that during the baptism of Jesus that the spirit of God descended on Jesus Christ like a dove and God spoke from heaven. According to Bro Eli he said the three are different.
According to John the baptist as the witness, he saw the Holy spirit like a dove upon Jesus on the river Jordan as the heaven open and he heard a voice from heaven saying this is my beloved son with whom am well pleased which shows that the three were different according to the book of Matthew 3 vs 15-16 and also the witness of John the baptist.
