In the power of the Holy Spirit, in the Name of Jesus, Peter was restored and refilled and ready to become the rock upon which the Church began.

"Therefore let all Israel be assured of this : God has made this Jesus, whom you crucified, both Lord and Messiah. When the people heard this, they were cut to the heart and said to Peter and the other apostles, brothers, what shall we do? Peter replied, 'Repent and be baptized everyone of you in the Name of Jesus Christ for the forgiveness of your sins  and you will receive the gift of the Holy Spirit.  The promise is for you and your children and for all who are far off, for all whole the Lord our God will call." (Acts 2:37-39)
