One thing I would like to say is that the Apostles taught more on "worship" than they did on
Acts 2:38. Everything comes into play when we worship.
Notice these scriptures -
Acts 1:4;
Ephesians 6:18;
Philippians 4:6 - "in prayer/
worship and supplication/petition", "with all prayer/
worship and supplication/petition"; "by prayer/
worship and supplication/petition".
Worship should always precede petition.
Notice when studying the word "prayer" that the definition "worship" G4335 is used more often.
We would see more things happen if we focused on "worship" rather than whether or not it is allowable to speak in tongues in church, at home or ever again after the initial infilling. JMO.
