Speaking in Tongues (Filling with the Holy Spirit)

Question details

Can you help me sort out the idea of being "Filled with the Spirit" and "Speaking in Tongues?" I am feeling a little pressured and am not sure what to make of it all. Ref: "They Speak with Other Tongues" by John Sherrill. Rec: Topical lecture "Charisma & Character." [Luke 11:9-13, Romans 5:5]
