In these first two verses of Genesis we are told that the Holy Spirit is God's creating power. God is one, and the Holy Spirit is the power of God. Everything that God does he does by means of his power, his Spirit (ref: John 4:24). Without the continual supply of God's Spirit, creation would not survive; a point made clear by the Apostle Paul when he spoke to the learned men of Athens (ref: Acts 17:24-25).
Two millennium ago, God's Spirit caused the virgin Mary to conceive resulting in the birth of Jesus, God's only begotten son. Jesus had the power given to him to perform signs and wonders as a means of spreading God's message. Jesus told his disciples that after his departure the Holy Spirit would come to them ("But you shall receive my power when the Holy Spirit has come upon you; and you shall be my witnesses in Jerusalem and in all Judea and Samaria and to the end of the earth" Acts 1:8 ).
These gifts were available between Jesus' ascension into heaven and the availability of the written Gospel. In the Bible it is referred to as the "counselor" (RSV) eg. John 14:26 "But the counselor, the Holy Spirit, whom the Father will send in my name, he will teach you all things, and bring to your remembrance all that I have said to you." In 1Cor 13 we are told that Spirit gifts, including speaking in tongues, would pass away and once the gospel became available in printed form such gifts ceased to be needed.
Your personal hope:- eternal life on earth, is through God's power; his Holy Spirit!
"...but when the perfect comes, the imperfect will pass away." 1Cor13:10
