1 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; 3Who 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.
Matthew 9:5-7 (ESV)
5 For which is easier, to say, ‘Your sins are forgiven,’ or to say, ‘Rise and walk’? 6 But that you may know that the Son of Man has authority on earth to forgive sins”—he then said to the paralytic— “Rise, pick up your bed and go home.” 7 And he rose and went home.
It is far easier to say, “Your sins are forgiven” than “Get up and walk” because the first of these commands cannot be disproved as easily. So to show that Jesus has the authority to make the easier claim, he demonstrates his miracle-working power that vindicates the harder claim. –Biblical Theology Study Bible Copyright © 2019 by Zondervan.
Peter gives us a great example of what it is to be “in Christ”.
Perhaps the lame man knew Peter and John were disciples of Jesus. Maybe he had heard them teaching in the Synagogue. Whatever the case, he did not resist when they took him by the hand and commanded him to get up. Following the example of Jesus, Peter and John imitated what took place in Matthew 9:5-7.
I choose the example in Matthew not only because it mirrors the Acts 3 actions, but because it Scripturally shows the way faith in Jesus can work through His disciples.
We know that faith in Him provides healing of our souls through the purging of our sins, but do we also know that same faith has the ability to heal the physical ailments brought about by that sin?
John 14:12-14 (ESV)
“Truly, truly, I say to you, whoever believes in me will also do the works that I do; and greater works than these will he do, because I am going to the Father. 13 Whatever you ask in my name, this I will do, that the Father may be glorified in the Son. 14 If you ask me anything in my name, I will do it.
View this not through personal experience, but simply for what it says. Commentaries tell us that more people were affected by the message of Christ through the disciples than through the entire ministry of Jesus. That miracles were a part of that message is evident here. In verse 16 Peter makes it clear, faith in His Name still produces miracles.
