Mark 16:17; These signs will accompany those who have believed: in My name they will cast out demons, they will speak with new tongues;
Mark 16:18; they will pick up serpents, and if they drink any deadly poison, it will not hurt them; they will lay hands on the sick, and they will recover.”
James 5:14; Is anyone among you sick? Then he must call for the elders of the church and they are to pray over him, anointing him with oil in the name of the Lord;
James 5:15; and the prayer offered in faith will restore the one who is sick, and the Lord will raise him up, and if he has committed sins, they will be forgiven him.
James 5:16; Therefore, confess your sins to one another, and pray for one another so that you may be healed. The effective prayer of a righteous man can accomplish much.
1 Cor 12:4; Now there are varieties of gifts, but the same Spirit.
1 Cor 12:5; And there are varieties of ministries, and the same Lord.
1 Cor 12:6; There are varieties of effects, but the same God who works all things in all persons.
1 Cor 12:7; But to each one is given the manifestation of the Spirit for the common good.
1 Cor 12:8; For to one is given the word of wisdom through the Spirit, and to another the word of knowledge according to the same Spirit;
1 Cor 12:9; to another faith by the same Spirit, and to another gifts of healing by the one Spirit,
1 Cor 12:10; and to another the effecting of miracles, and to another prophecy, and to another the distinguishing of spirits, to another various kinds of tongues, and to another the interpretation of tongues.
1 Cor 12:11; But one and the same Spirit works all these things, distributing to each one individually just as He wills.
If you've never seen a miracle of healing, I might suggest you try a different church.
Stephen was not an apostle.. but yet he did miracles, great wonders, and signs among the people ( Acts 6:8; )
How about Barnabas? he wasn't one of the original 12. (Really Paul wasn't either) ( Acts 14:14; )
