God never asked us to do anything specific in His name other than be obedient. For Peter, his obedience called for him to give all he had to the crippled man. In verse 6 it says, Then Peter said, “Silver or gold I do not have, but what I do have I give you. In the name of Jesus Christ of Nazareth, walk.” While riches may provide means to serve God, the only thing He really asks of us is to trust in Him and give all He has provided us to give.
