The Miracles of Jesus Christ And His Apostles in the Bible

Jesus performed mighty miracles when he was in this world.

Jesus came to Nazareth, where he had been brought up; and, as his custom was, he went into the synagogue on the sabbath day, and stood up to read. The scroll of the prophet Isaiah was handed to Jesus. He opened the scroll, and found the place where it was written, "The Spirit of the Lord is on me, because he has anointed me to proclaim good news to the poor. He has sent me to release the captives, restore sight to the blind, deliver those who are crushed, and to proclaim the acceptable year of the Lord." He closed the scroll, gave it back to the attendant, and sat down. The eyes of all in the synagogue were fastened on him. And he began to say unto them, this day is this scripture fulfilled in your ears - Luke 4:16-21.
Jesus introduced himself and the fact that he had arrived in full power and glory. Great things were about to be spoken and done in Israel. All miracles from God happen for a reason. They have purpose. They're not simply reactionary works of the supernatural powers that God possesses. They are targeted with the Big Picture of God's plan of redemption.

Jesus called unto him his twelve disciples and gave them power to perform Miracles

And when he had called unto him his twelve disciples, he gave them power against unclean spirits, to cast them out, and to heal all manner of sickness and all manner of disease.Heal the sick, cleanse the lepers, raise the dead, cast out devils: freely ye have received, freely give.Provide neither gold, nor silver, nor brass in your purses,Nor scrip for your journey, neither two coats, neither shoes, nor yet staves: for the workman is worthy of his meat.And into whatsoever city or town ye shall enter, enquire who in it is worthy; and there abide till ye go thence.And when ye come into an house, salute it.And if the house be worthy, let your peace come upon it: but if it be not worthy, let your peace return to you.And whosoever shall not receive you, nor hear your words, when ye depart out of that house or city, shake off the dust of your feet.Verily I say unto you, It shall be more tolerable for the land of Sodom and Gomorrha in the day of judgment, than for that city.Behold, I send you forth as sheep in the midst of wolves: be ye therefore wise as serpents, and harmless as doves.But beware of men: for they will deliver you up to the councils, and they will scourge you in their synagogues;And ye shall be brought before governors and kings for my sake, for a testimony against them and the Gentiles.But when they deliver you up, take no thought how or what ye shall speak: for it shall be given you in that same hour what ye shall speak.For it is not ye that speak, but the Spirit of your Father which speaketh in you.

But ye shall receive power, after that the Holy Ghost is come upon you: and ye shall be witnesses unto me both in Jerusalem, and in all Judaea, and in Samaria, and unto the uttermost part of the earth. - Acts 1: 8

And when the day of Pentecost was fully come, they were all with one accord in one place. And suddenly there came a sound from heaven as of a rushing mighty wind, and it filled all the house where they were sitting. And there appeared unto them cloven tongues like as of fire, and it sat upon each of them. And they were all filled with the Holy Ghost, and began to speak with other tongues, as the Spirit gave them utterance. - Acts 2:1- 4

Verily, verily, I say unto you, He that believeth on me, the works that I do shall he do also; and greater works than these shall he do; because I go unto my Father. - John 14: 12
