Christians today should be clear about a couple of things which are consistent with the Bible:
1. God is doing miracles daily, which no even one hears about. The primary miracle which God wants to see is sinners coming to repentance and being saved daily, since there is joy in Heaven over these miracles. And the prayer of faith is still valid for God to move His hand (if He so chooses) for healing or for even raising the dead.
2. Miracle workers have ceased, and you will not find any within the churches today. Were this not so, the hospitals would be empty. That is because signs, wonders and miracles accompanied the Gospel of Christ when it was introduced, and they authenticated the fact that (a) the apostles and their companions were sent by God and (b) that the Gospel was as supernatural as the miracles themselves.
I am become a fool in glorying; ye have compelled me: for I ought to have been commended of you: for in nothing am I behind the very chiefest apostles, though I be nothing. Truly the signs of an apostle were wrought among you in all patience, in signs, and wonders, and mighty deeds. (2 Cor 12:11,12)
Therefore we ought to give the more earnest heed to the things which we have heard, lest at any time we should let them slip. For if the word spoken by angels was stedfast, and every transgression and disobedience received a just recompence of reward; How shall we escape, if we neglect so great salvation; which at the first began to be spoken by the Lord, and was confirmed unto us by them that heard him; God also bearing them witness, both with signs and wonders, and with divers miracles, and gifts of the Holy Ghost, according to his own will? (Heb 2:1-4)
Since the Jews were to receive the Gospel first, and the Jews always looked for signs, God provided them with miracles and miracle workers. (Just as Christ authenticated Himself and His Gospel by His numerous miracles). But after the majority of Jews rejected Christ, there was no need for miracle workers. That is because the Gospel itself is the power of God unto salvation (Rom 1:16)
As Abraham said to the rich man in Hades: If they hear not Moses and the prophets, neither will they be persuaded, though one rose from the dead. (Lk 16:31) And Moses had already told the world that God would raise up a Prophet (Christ) whose words were to be obeyed (regardless of miracles):
The LORD thy God will raise up unto thee a Prophet from the midst of thee, of thy brethren, like unto me; unto him ye shall hearken;...I will raise them up a Prophet from among their brethren, like unto thee, and will put my words in his mouth; and he shall speak unto them all that I shall command him. And it shall come to pass, that whosoever will not hearken unto my words which he shall speak in my name, I will require it of him. (Deut 18:15,18,19)
