A few observations:
1. I believe Hopeful may have been on the right track. To experience God, do the will of God.
What is the will of God?
To love God with everything you've got, and love your neighbor as you would love yourself. We know this is always the will of God.
Well, I think you're mistaking effect for cause, here, a bit. What is "experiencing God," exactly? It is experiencing all the things the Bible says we can - and should - experience of
the life and work of the Holy Spirit within us and through us to all those around us. It's by the Person of the Holy Spirit that we are convicted about our sin (
John 16:8; Revelation 2-3), taught the eternal, divine Truth of God (
John 14:26; John 16:13; 1 Corinthians 2:10-16), strengthened in times of testing and temptation (
Philippians 2:13; Philippians 4:13; Ephesians 3:16; Romans 8:13), comforted in seasons of sorrow and pain (
2 Corinthians 1:3-4), and transformed into the "image of Christ" (
Romans 8:29; 2 Corinthians 3:18: Galatians 5:22-23). The Holy Spirit also glorifies God within the heart and mind of every believer (
John 16:14), causing them to love the brethren (
1 John 3:14), to hunger for God's word (
Jeremiah 15:16), to hate sin (
1 John 2:3-6; Ephesians 5:1-13; 1 Corinthians 6:19-20); , and to desire (love) God more and more as every day passes (
Romans 5:5; Galatians 5:22-23).
As the Holy Spirit works in these ways, producing these effects in the born-again believer, they are properly equipped to "do the will of God," and do so, actually, joyfully and as naturally as breathing.
2. Slain in the spirit is not biblically based on the gift of tongues. I see no Scriptural references linking slaying/tongues as possible or ever practiced as a church event. That makes me skeptical. The instances Hawkman pointed out were direct encounters with Jesus, or an angel of the Lord. They, Paul and John, were not "slain" as they were fully aware of what was happening.
I'm skeptical, too. The phrase "slain in the Spirit" does not appear in Scripture. There is no teaching on any such thing in God's word, either. The only people in the New Testament who behaved in anything like the way those "slain in the Spirit" do were those who were
demon-possessed.
3. Speaking in tongues, as practiced in Scripture, have not been practiced within the churches I have attended. The language spoken in Acts 2 is Galilean. It is heard by people, from 16-17 different languages if I recall, heard their native language. The speaker was speaking intelligible Galilean. The listener heard Galilean as if it were Egyptian, Greek, or whatever other language. This is the first practice of the gift in Scripture. As such, it is our benchmark for the practice. I have never seen this practice of tongues in any church service I have attended. The gibberish I hear, the slaying that I see on TV, comes across as self-aggrandizement.
Acts 2:4-13
4 And they were all filled with the Holy Spirit and began to speak with other tongues, as the Spirit was giving them utterance.
5 Now there were Jews living in Jerusalem, devout men from every nation under heaven.
6 And when this sound occurred, the crowd came together, and were bewildered because each one of them was hearing them speak in his own language.
7 They were amazed and astonished, saying, "Why, are not all these who are speaking Galileans?
8 "And how is it that we each hear them in our own language to which we were born?
9 "Parthians and Medes and Elamites, and residents of Mesopotamia, Judea and Cappadocia, Pontus and Asia,
10 Phrygia and Pamphylia, Egypt and the districts of Libya around Cyrene, and visitors from Rome, both Jews and proselytes,
11 Cretans and Arabs—we hear them in our own tongues speaking of the mighty deeds of God."
12 And they all continued in amazement and great perplexity, saying to one another, "What does this mean?"
13 But others were mocking and saying, "They are full of sweet wine."
So, the first verse from the passage above from
Acts 2 says: "...and began to speak with
other tongues...". Not "Galilean." Those to whom the Spirit-filled disciples spoke heard their own language issuing from the disciples. Some mocked this miracle of language, thinking the Spirit-filled disciples were drunk. A variety of languages being spoken by them, their speech, apparently, resembled the babble of a badly-inebriated person. This mocking indicates to me that the miraculous speech of the disciples was not a single, common language spoken by the disciples but heard by their audience in their own languages; rather it was a variety of languages the disciples spoke, Parthians hearing their language from some of the disciples, Egyptians hearing their language from other of the disciples, Cretans hearing their own language from still other of the disciples, and so on.
