I was told that what I was witnessing at a revival meeting was 'laughter of the spirit'.
What is this? Is this truly from the Holy Spirit? If I don't believe it is from the
Holy Spirit, am I blaspheming? I am confused and have been worried about this for
a long time.
First of all I would suggest to you to relax. I see no reason for you to be concerned of blaspheming the Holy Spirit. An act of blaspheming of the Holy Spirit is shown in Scripture. It was done during the time of Jesus’ ministry by the religious leaders of the time. This act of blaspheming the Holy Spirit that the Pharisees did in that day occurred because after actually watching Jesus cast out a demon, they refused to believe it was through the work of the Holy Spirit. They said it was from the devil. It wasn't their words that condemned them it, but what was in their hearts. Just because you are told by man that something THEY think is blasphemous doesn’t make it so. In fact more than likely what you are witnessing is people caught up in the emotions of the event.
God knows our hearts. Pray for answers. Ask God to have the Holy Spirit strengthen your knowledge and faith.
To attempt to answer your questions about 'laughter of the spirit', we should test every spirit to see if it is of God. First, lets look at some scriptural aspects of the Holy Spirit. By doing this, we can test this concept of 'laughter of the spirit';
But the fruit of the Spirit is love, joy, peace, patience, kindness, goodness, faithfulness, gentleness and self-control. Gal. 1:22-23
Notice the words, peace, patience, gentleness and self-control. From what you saw and heard that day at the revival, you would have to ask yourself, do these things agree with scripture? It doesn't sound like it does. There is no scripture that I am aware of that specifically gives support for that kind of 'laughter of the Spirit'.
As far as your confusion on these things, again it is because you, as I are learning, and that's ok. We need to pray to God for these answers, and always remember;
For God is not the author of confusion but of peace, as in all the churches of the saints. 1 Cor. 14:33
