Speaking in Tongues

At bible study yesterday, the pastor was speaking about being filled with the Holy Spirit. And praying to heaven through the Holy Spirit in tongues is a language only GOD can understand; like a prayer language. After being saved, then you must get to know the Holy Spirit. Many of us Christians fall short of being Holy Ghost filled. See scriptures below:

ACTS chapter 19 verses:

2 He said unto them, Have ye received the Holy Ghost since ye believed? And they said unto him, We have not so much as heard whether there be any Holy Ghost.

3 And he said unto them, Unto what then were ye baptized? And they said, Unto John's baptism.

4 Then said Paul, John verily baptized with the baptism of repentance, saying unto the people, that they should believe on him which should come after him, that is, on Christ Jesus.

5 When they heard this, they were baptized in the name of the Lord Jesus.

6 And when Paul had laid his hands upon them, the Holy Ghost came on them; and they spake with tongues, and prophesied.

I prayed in tongues for the first time yesterday after church members were praying for me on the alter. I felt the Holy Spirit at church, but it wasn't until I got home and got into the shower, I was able to speak in tongues. I still need to continue to practice speaking in tongues until I'm very comfortable doing it any time and any where. 12-6-18
