There are miracles that happen even today - healings, oh - how many cases where the doctors and stumped and unable to explain. Saved from accidents supernaturally, working of miracles as an answer to prayer, etc.
The gifts of the Holy Spirit are listed in multiple epistles, and the churches operated in them! Even a worldly church like the Corinthian church - had the genuine gifts operating in the them.
1Cor 12:28 And God has appointed in the church, first apostles, second prophets, third teachers, then miracles, then gifts of healings, helps, administrations, [various] kinds of tongues. 1Cor 12:29 All are not apostles, are they? All are not prophets, are they? All are not teachers, are they? All are not [workers of] miracles, are they? 1Cor 12:30 All do not have gifts of healings, do they? All do not speak with tongues, do they? All do not interpret, do they? 1Cor 12:31 But earnestly desire the greater gifts. And I show you a still more excellent way.
The reason I believe that these gifts are not seen in many churches (and denominations) is because many believers have shut themselves off of them and do not believe that they are for today.
30 years ago, these gifts were very operational in many churches that I know.
Like many truths of the scriptures were lost over the dark ages - such as the truth of salvation, emphasis on holiness in the church - which were later re-discovered during the Reformation and other revivals, the truth that the gifts of the Holy Spirit are for the churches today would resurface when people believe the scriptures and "earnestly desire them".
