If we don't agree on anything more that the fact that we need to seek God more and draw closer to Him, that would still be enough.
When the initial power of the Holy Spirit came upon me and equipped me for ministry, I never spoke in tongues. Truthfully, I didn't know I "had" to. I hadn't read the Acts of the Apostles yet for I was still a very new Christian. I simply loved the Lord fervently and had an intese desire to serve Him in whatever capacity He had for me. The first time His power came upon me, it took me to the floor in wave after wave of glory. All I could do was weep aloud and cry "Jesus!" over and over again. My wife was there, she can attest to it. I had to be driven home from the assembly of believers and put to bed. I am not a man given to extreme shows of emotion, so this shocked many people.
Shortly after this event, God called me to preach His word with signs and wonders following both in the church and on the street. I will not go into details here, for I am uncomfortable speaking about these things with the fear of taking the glory from God. But I can put you in touch with some of the people who were there, and will tell you of things the Holy Spirit did that will absolutely amaze you. And throughout it all, no one - including myself - ever spoke in a tongue.
Seeing all the signs and wonders and power on the ministry, I was eventually approached by a pastor who wanted to plug me into the Assemblies of God. He brought me to an annual conference/convention in Waxahatchie, Texas along with my wife and a few others from our church. One of the "workshops": "The Baptism in the Holy Ghost". A man taught that unless you've spoken in tongues you were not genuinely filled with the Holy Spirit according to scripture. So convincing was he, that I and about 70 others believed him, and went forward for him to lay his hands on us and pray that we would receive the genuine infilling. He coached us and encouraged us to just focus on Jesus, and let any syllable roll off our tongues that wanted to. Only make sure it wasn't English. It had to be a foreign sound.
After about 20 minutes of standing up there and having people shout over me and catchers standing behind me, I began to become disillusioned and just wanted to go back to my seat and sit down. Ah, but people were watching me! Youth from my church! So I faked it. I spoke some words prasing God in Russian (my second language), and the man coaching me was satisfied. When we returned to our home church that Sunday, the pastor told everyone that Brother Paul was now "filled with the Holy Spirit" and everyone cheered and applauded. But I knew it was a fake, and I never told anyone but my wife. And now SermonIndex.
A few years later I was accepted into the Assemblies of God as a certified minister and given the title "evangelist" and "reverend". My pastor vouched for my Spirit Baptism before the board, and attested to the subsequent power connected to my ministry. But he forgot that these signs and wonders were present for years in my ministry before going to Waxahatchie and being coached to speak in a foreign tongue.
I have since relinquished my credentials with the AG due to various issues, but believe they are a good organization and mean well. All throughout the Bible and church history we see that God is sovereign in His dispensations and giftings, and that when we try to put Him in a mold He confounds our theories with present, irrefutable reality. He does what He pleases when it is said and done, and no one can command, categorize or legislate His sovereign will otherwise -- especially when it comes to the moving, birthing-again and filling of the Holy Spirit.
