“But you shall receive power when the Holy Spirit has come upon you; and you shall be witnesses to Me in Jerusalem, and in all Judea and Samaria, and to the end of the earth.” (Acts 1:8 NKJV). When you receive the Holy Spirit, you receive power to witness. There are lots of books, seminars, and conferences on witnessing. They may give you some ideas on how to approach witnessing, but you can only be effective witnesses with the power of the Holy Spirit. When we witness or share the Gospel. It will fall flat without the Holy Spirit. He is the one who speaks to hearts. He is the one who can reveal the gospel of grace to a heart. Only He can tear down misconceptions and destroy the yokes of bondage on a person. That power is within us, and He uses us to share with others, and He works alongside us to be effective.
