Some things are not widely publicized, wisely.
Either GWB is a tongue-speaker or he's not. Evidence is he's not. What's your definition of "spirit-filled"?
Not about to get into THAT
with you and your sensibilities!!! LOL.
Holy Spirit knows.
Jesus knows.
The Father knows.
Billy Graham spoke of all Believers needing to be refilled daily.
A good Biblical position, imho.
I know now they invoke mass hallucination and wait for "the spirit" to fall. The aim is to fall down unconscious in a trance and whoever is out the longest wins. How this has anything to do with worshipping the Father in spirit and in Truth, which per the Bible, clearly means to study the Word of God, is beyond me.
Whoever is a believer, is indwelt by the Holy Spirit, and if the believer sins, then repents from that sin by confession per 1st John 1:9, that believer is again in fellowship with God. The believer may then be filled with the Holy SPirit in many different fashions, just as the types of gifts of the spirit may vary from believer to believer.
Being filled with the Spirit, doesn't necessarily imply sensationalism, emotion, nor experience.
