Miracles served a number of important purposes. Most basic, they helped to establish or confirm the fact that a man was receiving power and support from God. (Ex 4:1-9) Both with Moses and Jesus people drew this correct conclusion. (Ex 4:30, 31; John 9:17, 31-33) Through Moses, God had promised a coming prophet. Jesus’ miracles helped observers to identify him as that one. (Deut 18:18; John 6:14) When Christianity was young, miracles worked in conjunction with the message to help individuals to see that God was behind Christianity and had turned from the earlier Jewish system of things. (Heb 2:3, 4) In time miraculous gifts present in the first century would pass away. They were needed only during the infancy of the Christian congregation.—1Cor 13:8-11.
In reading the history of the Acts of Apostles, we see that Jehovah’s spirit was working mightily, speedily, forming congregations, getting Christianity firmly established. (Ac 4:4; chaps 13, 14, 16-19) In the few short years between 33 and 70 C.E., thousands of believers were gathered in many congregations from Babylon to Rome, and perhaps even farther west. (1 Peter 5:13; Rom 1:1, 7; 15:24) It is worthy of note that copies of the Scriptures then were few. Usually only the well-to-do possessed scrolls or books of any sort. In pagan lands there was no knowledge of the Bible or the God of the Bible, Jehovah. Virtually everything had to be done by word of mouth. There were no Bible commentaries, concordances, and encyclopedias readily at hand. So the miraculous gifts of special knowledge, wisdom, speaking in tongues, and discernment of inspired utterances were vital for the congregation then. (1 Cor 12:4-11, 27-31) But, as the apostle Paul wrote, when those things were no longer needed, they would pass away.
A Different Situation Today. We do not see God performing such miracles by the hands of his Christian servants today, because all needed things are present and available to the literate population of the world, and to help those who cannot read but who will listen, there are mature Christians who have knowledge and wisdom gained by study and experience. It is not necessary for God to perform such miracles at this time to attest to Jesus Christ as God’s appointed deliverer, or to provide proof that He is backing up His servants. Even if God were to continue to give his servants the ability to perform miracles, that would not convince everyone, for not even all the eyewitnesses of Jesus’ miracles were moved to accept his teachings. (John 12:9-11) On the other hand, scoffers are warned by the Bible that there will yet be stupendous acts of God performed in the destruction of the present system of things.—2 Peter 3:1-10; Rev chaps 18, 19.
In conclusion, it may be said that either those who deny the existence of miracles do not believe there is an invisible God and Creator or they believe that he has not exercised his power in any superhuman way since creation. But their unbelief does not make the Word of God of no effect. (Rom 3:3, 4) The Biblical accounts of God’s miracles and the good purpose that they accomplished, always in harmony with the truths and principles found in his Word, instill confidence in God. They give strong assurance that God cares for mankind and that he can and will protect those who serve him. The miracles provide typical patterns, and the record of them builds faith that God will, in the future, intervene in a miraculous way, healing and blessing faithful humankind.—Re 21:4.
