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. Here we see people where influenced by what happened to this lame man who know is walking shouting and praising the Lord, who they know was lame from birth. He is now a vessel the Lord is using to bring glory to the Kingdom of God. Not only was his body healed, his total being was different. Gods mercy is perfected when we are abiding in the sanctification of the Lords love, mercy and grace. They were astonished at this wonderful miracle and in total amazement, greatly wondering. Just like earlier when they were all filled with the Holy Spirit speaking in a new tongue. They could not believe people could talk in a language they had not learned and here they are amazed at this miracle and wanted to hear what happened.

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? Remember Peter was watching and seeing so he saw the questioning and know what happen, so began to preach giving a message greater than what Solomon could deliver. Here he saw the fallow ground, ready to accept the seed of the Gospel that needed to be sown. He saw the people adore this miracle and wanted to direct them to the healer, Jesus the Christ who had appeared to them forty days after He had arisen from the grave and left giving them the promise of the Holy Spirit. He did not want them to see Him, or John, but Jesus’s Holy Spirit that gave new life to anyone that believes to rise and walk. It is not because of a preacher, or evangelist, or prophet we are saved, but Jesus only. It is certainly not us, but the Lords own invention that seals us into His family. Here he is talking to men of Israel. Why are you so surprised and marveled? This is what Christ did many times even when He raised Lazarus from the dead. We need to be convinced God is alive and wants to do mighty works among us. We are a church that Is alive for we are humbled by many time how few accept this way, truth and life
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. Peter is not praising his name, but in the name of Jesus Christ, God Son as the holy Spirit gives his tongue the ability to speak to where it grows and God name is glorified, as it was through Abraham, Isaac, Jacob and Jesus Christ our Lord. Notice Peter says boldly.
¹⁴ But ye denied the Holy One and the Just, and desired a murderer to be granted unto you; You denied Jesus and delivered Him up to be crucified. Pilate wanted to let Him go, but you turned against Him and Said, Crucify Him, who He could have been your king. Look today at how many deny the Lord wants to rule and reign, but thinks He is a dictator preventing you from doing your thing.  Here your worse than Pilate, you denied the holy one the just one who proved who He was, by being alive and now seeing this miracle of the lame man walking and leaping for joy. Yes you killed a murderer a destroyer of life and destroyed the Savior, the author of Life. You killed the prince of life, not only forsook but rebelled against your own mercies. He could have been your life.
¹⁵ And killed the Prince of life, whom God hath raised from the dead; whereof we are witnesses. What a shocking statement Peter embarrassed them to let them see what a terrible thing they did yet God raised Him from the dead and appeared for 40 days to prove to all He was alive that was witnessed by thousand’s. So now he proves it was this same Jesus who gave this lame man a healing.
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. It is our faith in God that makes us strong to stand up and walk and leap for joy, so that all who see and hear can also believe. Here Peter and John had no doubt seen this man but did not know him until he obeyed the command rise up and walk. Lord help us to not get to the place where we want to cop out but want to refresh our faith and be renewed in our faith to where we completely surrender to God will again. Not by power but by the will of God or spirit of God. This is the gift that God gave to every one of us when we accept abiding in Him, so we produce good will and peace to all. Not only did he receive a healing in the body but in his souls five senses, Memorynot lame walk and leap now. His imaginationwas real, reality was I can walk and leap. His reasonwas by faith I will stand. His consciencewas alive he was excited about Peter and John stopping to even talk with him. Then his affection was full of excitement yelling a leaping for joy. Lord help us to be mentally sound in our minds so we are not sick with the pains of the world.
Note now how he addresses them
¹⁷ And now, brethren, I wot that through ignorance ye did it, as did also your rulers. Calling them Brethren is a complement for they were alive and he did not cast them aside, but included them as people needing help. Do you want to help people become better; praise them, lift them up. You did what you did for you did not see this that your seeing now. Here Peter was applying to their senses for they are now seeing the wonder of Gods healing power. Then he goes on to say;
