I know. You are quite right. But I'm not primarily speaking to the deaf anyway. People often see and hear better when they evesdrop or lurk.
What's been persistently amazing to me is the number of believers--especially in foreign lands--who "stumble" onto tongues and other ecstatic EXPERIENCES totally independently led of Holy Spirit.
Some even have and know minimal Bible. Some have ONLY the Bible and just take it at face value for what it says and try in their humble, child-like way to apply it. And BOOM, GOD ALMIGHTY BREAKS THROUGH TO THIS TIME AND SPACE IN THEIR INTERESTS IN LOVING RESPONSE TO THEIR PRAYERS AND THE DESIRES OF THEIR HEART--often down to very petty detail levels. What an Awesome God!
You have said a mouthful here, as the maestro knows. (How gracious He is to his priests.)
