Why do we need the Holy Spirit? Jesus said it is the Spirit who convicts the world of sin, of righteousness and of judgment to come (John 16:8). - It is not the preacher who convicts of sin, it is the Holy Spirit! Without this 'Baptism' we are powerless and ineffective. The whole purpose of the Baptism in the Holy Spirit is to fill us with power so that we can win the lost! The 'Baptism' is not so that we can sit at ease in church in a 'holy huddle', but to preach the Gospel with power and authority! What was the first thing Peter did when he was baptised in the Spirit? He won 3000 for the Kingdom! What did you do when you first received the Holy Spirit?!
