When Jesus was on earth he often performed miracles. This was part of the portfolio of evidence that Christians believe that convinces them that Jesus was more than a great man, he is the Son of God.
After the Lord Jesus returned to heaven he continued to perform miracles, not in person, but through the Church on earth. I personally believe that the time for miracles is now past (I mean physical healing and the raising of dead people to life). I believe this for various biblical reasons which are not relevant in this posting.
I still believe that God can do miracles he just doesn't give people individual gifts to do them. When Christians pray God often responds by healing but it is not guaranteed.
THE GREATEST MIRACLE
The greatest miracle of all is described in this chapter. It's not in the first section (verses 1-10) wonderful though that is! It is the miracle of salvation. Verse nineteen describes how it happens -"Repent ye therefore, and be converted, that your sins may be blotted out". This is the biggest miracle. Sin haunts us. Sin when it is finished ends in death. Death stalks us until we fall into it's powerful grip. Fear and tears are part and parcel of this life but the Lord Jesus came to purchase and provide eternal life by his death on the cross. He said "I am come that they might have life".
The price to satisfy the holy demands of God for justice and payment for sin was paid by the death of the Lord Jesus on the cross - "Christ died for our sins" so says the word of God. The sacrifice of Christ ensures that you can be saved, safe and ready to die and meet God.
I hope by this stage you are asking what must I do! That's what the people asked in the Acts 3. The reply is quoted above and in the text below - Repent....and be converted. Salvation comes when you admit your sin, change your mind about God and your sin and trust Christ to save you. Conversion is the change that takes place straight away as a result.
Please read the passage and if God speaks to you repent of your sin and trust Christ for salvation.
Acts 3Authorized (King James) Version (AKJV)
3 Now Peter and John went up together into the temple at the hour of prayer,being the ninth hour. 2 And a certain man lame from his mother’s womb was carried, whom they laid daily at the gate of the temple which is called Beautiful, to ask alms of them that entered into the temple; 3 who seeing Peter and John about to go into the temple asked an alms. 4 And Peter, fastening his eyes upon him with John, said, Look on us. 5 And he gave heed unto them, expecting to receive something of them. 6 Then Peter said, Silver and gold have I none; but such as I have give I thee: In the name of Jesus Christ of Nazareth rise up and walk. 7 And he took him by the right hand, and lifted him up: and immediately his feet and ankle bones received strength. 8 And he leaping up stood, and walked, and entered with them into the temple, walking, and leaping, and praising God. 9 And all the people saw him walking and praising God: 10 and they knew that it was he which sat for alms at the Beautiful gate of the temple: and they were filled with wonder and amazement at that which had happened unto him.
11 And as the lame man which was healed held Peter and John, all the people ran together unto them in the porch that is called Solomon’s, greatly wondering.12 And when Peter saw it, he answered unto the people, Ye men of Israel, why marvel ye at this? or why look ye so earnestly on us, as though by our own power or holiness we had made this man to walk? 13 The God of Abraham, and of Isaac, and of Jacob, the God of our fathers, hath glorified his Son Jesus; whom ye delivered up, and denied him in the presence of Pilate, when he was determined to let him go. 14 But ye denied the Holy One and the Just, and desired a murderer to be granted unto you; 15 and killed the Prince of life, whom God hath raised from the dead; whereof we are witnesses. 16 And his name through faith in his name hath made this man strong, whom ye see and know: yea, the faith which is by him hath given him this perfect soundness in the presence of you all. 17 And now, brethren, I wot that through ignorance ye did it, as did also your rulers. 18 But those things, which God before had shewed by the mouth of all his prophets, that Christ should suffer, he hath so fulfilled.
19 Repent ye therefore, and be converted, that your sins may be blotted out, when the times of refreshing shall come from the presence of the Lord; 20 and he shall send Jesus Christ, which before was preached unto you: 21 whom the heaven must receive until the times of restitution of all things, which God hath spoken by the mouth of all his holy prophets since the world began. 22 For Moses truly said unto the fathers, A prophet shall the Lord your God raise up unto you of your brethren, like unto me; him shall ye hear in all things whatsoever he shall say unto you. 23 And it shall come to pass, that every soul, which will not hear that prophet, shall be destroyed from among the people. 24 Yea, and all the prophets from Samuel and those that follow after, as many as have spoken, have likewise foretold of these days. 25 Ye are the children of the prophets, and of the covenant which God made with our fathers, saying unto Abraham, And in thy seed shall all the kindreds of the earth be blessed. 26 Unto you first God, having raised up his Son Jesus, sent him to bless you, in turning away every one of you from his iniquities.
