Well my opinion,
I grew up catholic, when I decided around thirteen I wanted to go to an assembly of God (Pentecostal) church. I went with friends and every time I went I felt I understood the bible more and more, which was weird because in the catholic church I was to study the verses (homework and all).
At one of the services the pastor invited anyone to come forward and pray with him for their salvation. My friend went forward, she was a friend who was not a very good influence, while being prayed for infront of the whole congregation, she fell to the ground and began to shake perfusly. I freaked and ran to her, thinking she was having a seizure. An usher stopped me and said she is okay, it is the holy spirit entering. After she came to she cried hysterically. Ever since that day, she has followed the lord. Her and her husband are youth leaders at a church.
I still attend that church where this took place, and I rarely see or hear anyone speaking in tongues. What I do see is a strong passion to live intentionally for our lord. Highly motivated soldiers of god working to show who god is to others through themselves, as well as spreading the word of God. A church who invests in the children, community, and the world.
To list a few recent things our church has done
We phyisically and finanicially remodeled a church a few hours away, we send missionaries all over the world, we bought over two thousand pounds of food and gave it away, we run a skate park compition/carnival, we run a car show, we gather once a year to clean up or aide in projects for random homes in the area that appear to need help, feed and serve the homeless, and battered women on the holidays, food and hygiene pantry all year, and so many more.
All this is done through God, and we spread his love to as many as possible.
