Theologically speaking, there are words you will never find in the bible , but you will see the bible making reference to them, and one of those words is rapture, there was no place in rapture was mentioned in the bible, but we get to know about rapture through the same bible.
The bible made us to understand that God is one, but he manifest himself in three persons, and the holy spirit is one of them.
The holy spirit is so important to the point Jesus emphasized so much about him, The holy spirit is God, he is not like God, he is God, the holy spirit represent the presence of Jesus on earth, and he is the manifestation and also the revealer of the power of God.
