As Peter and John go to the temple to pray, they are accosted by a lame man for alms. Instead of giving money, he is healed. This was done in front of very “religious” people – the kind of people that don’t hear very well. They know what they know, usually as taught by someone else. Christians, on the other hand, have the Bible as their authority. Peter trusted the Lord would heal him and rebuked the people for wanting to give credit to them, based on Peter and John’s own power and godliness.
