Read Acts 2:22-41
Peter replied, “Each of you must repent of your sins and turn to God, and be baptized in the name of Jesus Christ for the forgiveness of your sins. Then you will receive the gift of the Holy Spirit. Acts 2:38 (NLT)
Our only hope is in the work of Jesus Christ on the cross. Only through Jesus’ righteousness can we have the Holy Spirit dwell within us. That’s the key difference between people of the Church, and people of the World. People in the Church are people who repent of their sins and believe and trust in what Jesus has done for them, not in any good work of their own.
