I Cor. was written to: A. A New Testament Church, and therefore relevant. B. A group of Apostles, and we should ignore it. ? Pick a winner.
I invite you to search this site for miracles, wonders, signs, etc and I have explained thoroughly what I mean.
The point is this, as the Gospel spread so did the Spirit's regeneration. At the time of the Writings, the gifts like healing, prophesying, tongues, etc were relevant and of God but referred to as childish as the Spirit spread with the Gospel the months and years following Pentecost.
Noone living has witnessed any Scriptural gifts or signs or miracles apart from the greatest miracle and gift of God which is the regeneration of the Holy Spirit.
This tongues nonsense if mainly propagated by silly women laden with sins and emotional men IMO. Folks read emotional accounts or witness emotional outbursts and buy into this nonsense as signs from God or miracles, it is all rubbish.
