We just completed our series on the Holy Spirit at our Sunday Church services. In the last part of the series, we looked at the Baptism of the Holy Spirit.
Everyone who is born-again has the Holy Spirit dwelling in them. The bible says that we are sealed by the Spirit the moment that we are born-again (Ephesians 1:3). However the baptism of the Holy Spirit is a different experience. Jesus stated clearly that to be effective witnesses for Him, we need to be baptised or in-filled by the Holy Spirit (Acts 1:8). The two main points relating to this are outlined below.
 We have the Holy Spirit when we are born-again, but this is different from the baptism of the Holy Spirit. (Scriptures: Ephesians 1:3, Acts 1:8, Mathew 3:11, Acts 19:1-6)
 Receiving the baptism of the Holy Spirit. The pre-requisite for receiving this baptism is that you must be born again and ask God in faith. (Scriptures: Acts 2:38, Luke 11:13, Acts 2:4)
