When did the Holy Spirit come to earth?
Jesus promised to send a comforter to his disciples. That comforter was said to be the Holy spirit and it is because of this that some people come to belief or think that the Holy spirit came to earth after Jesus died and ascended to heaven. Some people even teach that Jesus had to ascend to heaven before the Holy Spirit could come to earth and dwell with his disciples and anyone that believes in him.
The Holy Spirit is expected to reveal some things to the disciples and even given them the power to do most things. The teaching of the trinity even equal the Holy Spirit as three in one in that God, the son, and the Holy Spirit are one. That is three different persons in one. That may be confusing that is why some Christians do not support the doctrine. This work is not about doctrines but to understand more about the Holy Spirit and when it came to earth to help mankind.
The Apostles we were said to had received power on the Pentecost day and they spoke in various tongues. The question is, was the Holy Spirit already operation on earth and helped men even before Jesus came or did Jesus die to actually make way for the Holy Spirit, the helper, to come?
We know that men worked with God before Jesus came to earth and most of these men had power or special gift that separated them from the crowd. Some people claim that the Holy Spirit had been known by various names like the Cherubim and seraphim among other names while some claim that these were not actually the Holy Spirit. However it is clear, from the words of David, that the Holy Spirit lived among men even before the coming of Jesus.
David said to God, “Take not your Holy Spirit from me” which means the Holy Spirit dwelled with him and he knew the benefits of the Holy Spirit that he did not want to loss.
The Holy Spirit had always been among men and had helped men though men may call it various names.
