Peter and John heal a lame man, giving Peter an opportunity to speak to the crowds concerning God's plan of salvation, revealed through the Old Testament prophets and culminating with the revelation and message of Jesus Christ and the eternal life he offers to everyone. As a result, Peter and John encounter persecution from the Saducees as they have to defend this miraculous healing through the power of the Holy Spirit. This miracle was used by God to authenticate Jesus, along with the use of fulfilled prophecy. In light of the persecution of Peter and John, we should view persecution for the sake of Christ as good and worth pleasing God for, as we rely on the boldness from the Holy Spirit to be spokespeople for God.
