What does Acts 3:2 mean?
Bartimaeus was begging at Jericho when Jesus met him on His way to Jerusalem (Mark 10:46–52). Jesus never condemns beggars, and He is clear that congenital defects are not "earned" because the person is sinful (John 9:1–7). The healing of the lame is a sign that the Messiah has come (Isaiah 35:6). Whether healed or not, the lame are welcome into God's kingdom (Luke 14:21).The location of "the Beautiful Gate" is uncertain. It being a "gate of the temple" doesn't mean that it goes directly into the building; the phrase "the temple" is often used to mean the entire top of the Temple Mount. Some think it is one of the gates in the temple itself, but no other source mentions "the Beautiful Gate" by name. It is unclear if the lame were allowed into the temple, although many believe they may have been banned. When David first captured Jerusalem, the inhabitants—the Jebusites—mocked that the lame and blind could fight off his army. After his victory, the saying, "The blind and the lame shall not come into the house" became popular, but in the context, this refers to Jebusites, not literal blind and lame people (2 Samuel 5:6–8). Men who were lame were not allowed to be priests (Leviticus 21:17–18), but the Mosaic law doesn't forbid the lame from entering the temple as worshipers.
Acts 3:1–10 illustrates one of the ''wonders and signs'' the apostles performed after receiving the Holy Spirit (Acts 2:43). The setting is completely mundane. As Jews, Peter and John go to the temple to pray and find a lame beggar they wish to help. As specially-empowered followers of Jesus, healing the man comes second nature. The act validates Peter's status as witness to Jesus (Acts 1:8), and he is ready with an explanation that ties the event to Jesus' call to repentance (Acts 3:11–26). This miracle, however, catches the attention of the Sanhedrin and starts the long road of church persecution (Acts 4).
Acts 3 is comprised of two sections: the healing of a lame man and the explanation of that healing. First, a man who has been lame his whole life approaches Peter and John to beg from them at the temple. When Peter heals him in Jesus' name, a crowd gathers around. Peter gives witness to Jesus (Acts 1:8) and tells the crowd that Jesus' authority and power healed this man. Looking back as modern readers, we see how, as the man's body symbolically ''repented,'' or turned away, from its broken form into freedom of movement, so the people can repent from their broken thoughts, actions, and beliefs, and find freedom from sin.
