After Jesus gave His disciples the charge to "go make disciples..." He told them to wait for a gift. He said "John baptized with water, but soon you will be baptized with the Holy Spirit..." this gift would give them power to be witnesses to the world.
This gift is for you and I as well.
The bible says that the disciples and many others "joined constantly in prayer..." before they received this gift. When they got the gift "all of them were filled with the Holy Spirit and began to speak in other tongues as the Spirit enabled them."
So how do we get this baptism?
We are baptized in water by asking the baptizer to submerge us in the water and by believing the work that God is doing in us.
So we are baptized in the Holy Spirit by asking the baptizer (Our Father in Heaven) to submerge us in the Holy Spirit by faith that He will do it.
So what's the next step?
Believe. Ask. Continue Asking.
Father God will enable you to receive this gift, and the Holy Spirit will enable you to be witnesses of who The Father, Jesus, and the Holy Spirit are to the ends of the earth.
Here are some places that you can have time to pray and seek after God with other believers:
