There is no limit to what a believer can do with help of the Holy Spirit. Among others, Holy Spirit empowers, comforts, and teaches his recipients.
The Bible reference
“But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth.”
(Act 1:8 KJV)
