Did your father speak Welsh before the alleged event? To whom was he ministering when he allegedly received this gift?I know my Dad recieved the Holy Spirit through none of the above ways. He went for a walk up the country road near where we lived which was on top of a hill and a whirlwind came and encircled him and he started speaking in tongues at such a speed he didn't think it was possible, and all he could say was "Yspryd Glân" (Holy Spirit. Literal translation = "Clean Spirit").
When he came back he was clearly a changed man!
In 1 Corinthians 12 through 14, Paul discusses miraculous gifts, saying, “Now, brothers, if I come to you and speak in tongues, what good will I be to you, unless I bring you some revelation or knowledge or prophecy or word of instruction?” (1 Corinthians 14:6). According to the apostle Paul, and in agreement with the tongues described in Acts, speaking in tongues is valuable to the one hearing God’s message in his or her own language, but it is useless to everyone else.
And why does it seem that "Speaking in Tongues" makes some think they are more "holy" than those who don't?
