With regards to Biblical things, we’ve seen various people giving their opinion on various things in the Bible. When there is confusion, it’s usually because the commenter does not know the Bible or the Father very well.
When someone tells you that you receive gift of the Holy Spirit when you confess Jesus as Lord, they are mistaken. They have not received the power of the Holy Spirit. Once you get the vehicle, you’ve got to get the fuel.
The Baptism of the Holy Spirit is a separate event that is evidenced by the gift of tongues and the other gifts of the Spirit. Acts 2 shows the infilling of the Holy Spirit is an event. Multiple believers in Acts confessed Jesus on their own but did not receive the power through the Holy Spirit until they were prayed for by a Spirit-filled believer.
The baptism of the Holy Spirit is a must for every believer.
