Acts 2:38 (NLT)
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."
Read 1 Peter and do your own study.
Determine an area of your life where you want a greater level of freedom and wholeness. Live towards holiness in that area.
