I prayed for a woman pastor and as I prayed she began to speak what I thought was Portuguese. I asked the translator what she was saying. He in turn listened for a minute and said “English?” I said no, and my translator told me she was not speaking Portuguese so we assumed she was speaking in tongues. Later, after we prayed for her, she asked if it was possible that she was speaking in the Spirit at that time. Come to find out she had never spoken in tongues before that moment! Praise God.
