I haven’t mentioned this before, but I attend a Pentecostal-leaning church. Although I do not consider myself to be a Pentecostal, the church is solid doctrinally and is committed to reaching out to the lost.
One of the distinguishing characteristics of Pentecostals is the belief that people are able to speak in tongues today. I’ve even seen this during some of the church services I’ve attended. Godly believers exist on both sides of the issue, which is why I have included a resource for each position below. Both speakers bring up good points and make a solid argument.
