“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.” (Acts 1:8)
We have already received the Holy Ghost; therefore, we have already received power to be Christ’s witnesses. We need to let the power of the Holy Spirit fill us so that we can be effective in witnessing.
“And when they had prayed, the place was shaken where they were assembled together; and they were all filled with the Holy Ghost, and they spake the word of God with boldness.” (Acts 4:31)
Evidence of the Holy Spirit’s filling here was that they spake the word of God with boldness. How we need the Holy Spirit to fill us so that we may do the same!
“And the disciples were filled with joy, and with the Holy Ghost.” (Acts 13:52)
