Understanding The Miraculous Gifts Of The Holy Spirit

God tells us clearly that these "gifts of the Holy Spirit" were to cease.  In I Cor. 12, the apostle Paul lists those gifts.  Then in the next chapter, he wrote: 1 Corinthians 13:8-12 (KJV) 8 Charity never faileth: but whether there be prophecies, they shall fail; whether there be tongues, they shall cease; whether there be knowledge, it shall vanish away. 9 For we know in part, and we prophesy in part. 10 But when that which is perfect is come, then that which is in part shall be done away. 11 When I was a child, I spake as a child, I understood as a child, I thought as a child: but when I became a man, I put away childish things. 12 For now we see through a glass, darkly; but then face to face: now I know in part; but then shall I know even as also I am known.
Notice that each gift was a "part", but when "the perfect" was come, the parts were to cease. The expression "the perfect" is from the Greek "to telion" which literally means: "complete, full-grown, fully developed." So, when the revelation of God's Word was completed, and confirmed, then the "parts" were done away.  Note that Paul says, "For now we see in a mirror, darkly; but then face to face; now I know in part; but then shall I know fully even also I was fully known" (I Cor 13:12). This is explained by James, "But be ye doers of the Word, and not hearers only, deluding your own selves.  For if any one is a hearer of the Word and not a doer, he is like unto a man beholding his natural face in a mirror; for he beholdeth himself, and goeth away, and straightway forgetteth what manner of man he was. But he that looketh into the perfect law, the law of liberty, and so continueth, being not a hearer that forgetteth but a doer that worketh, this man shall be blessed in his doing" (Jam 1:22-25). Some contend that these "gifts of the Spirit" were to continue until Christ comes, and we then see Him and the Father "face to face."  Yet, look at the passage again: "Now we see in a mirror, darkly, but then face to face" (I Cor 13:12). No one looks into a mirror to see God, or anyone else. We look into a mirror to see ourselves. To shave, to put on makeup, etc., we need to see "face to face." That is the purpose of the mirror. And the Word of God is "the perfect law of liberty" (Jam 1:25), a spiritual mirror, into which we look to see our spiritual condition as God reveals it in His Word. That is what Paul says in I Cor 13.
Because we have the revealed and written Word of God, confirmed (proved) by the miracles which the apostles did, we no longer need those "parts" which brought it into existence.  So they have ceased and been done away.  That includes all the miracles -- healing, raising the dead, etc.  So, yes, the age and purpose of miracles have ended. We have the completed Word of God confirmed by these miracles and therefore there is no more need for such miracles.
