This is one of my favorite chapters, here is shown the power of God, and true freedom. Pedro and Juan came from the ninth hour of prayer, which makes me suppose that they came full of the power of God, when the lame man they are left looking is with the intention of receiving something from them, something material. Pedro and Juan have the revelation of the spirit and tell him: I have no gold or silver but what I have I give you, in a few words they were saying I do not have what the system gives you, slavery, but I have something even greater and it is the freedom of Christ, that which does not make you dependent on any political or social system, so in the name of Jesus, get up and walk, at that precise moment the lame of the temple the beautiful was free, was saved.
There is power in Christ's name and christianity is all about poweR.
