Answer: True
Explanation: All help comes from God, it is only in him all good and perfect work can be done.
But know that we have three God in one. God the Father, God the son, and God the Holy Spirit.
Remember when Jesus left his disciples to ascend to heaven he ordered them to lock themselves inside a room until the holy spirit comes upon them. For it is written in Act1:8 " But ye shall receive power, after that the holy ghost is come upon you: and ye shall be witnesses into me both in Jerusalem, and in all judaea and in samaria, and into the uttermost part of the earth"
This is what jesus told his disciples, so we can conclude that all that was done was done with the power of the holy spirit working in them, to give God the glory.
You can also see in Act 9: 17 that Paul received the holy Spirit before he could do all he did through the name of Christ jesus.
Hope this clears your doubt about the holy spirit.
