The same is true for the baptism of the Holy Spirit. A Christian asks God for it and begin desiring it. Then as you’re praying, little phrases will pop up in your mind. You have to begin saying these out loud and this is a vehicle for the Holy Spirit. Then it’s like a flood will come upon you.
So, it takes asking, seeking, and having faith.
Salvation and the Baptism of the Holy Spirit are requirements/ tools (in essence) for ministry. The purpose is to get them and be fully equipped to live and minister. God will teach you as you go along.
All these other issues like OSAS Calvinism etc will fall be the wayside.
