Why is it important that Jesus says, "Peace be with you" to his disciples? Jesus said that he would have the Father send the Holy Spirit to help guide the disciples once he was gone. When Jesus returns, he tells them, "Peace be with you" and then breathes on them and says, "Receive the Holy Spirit. Whose sins you forgive are forgiven them, and whose sins you retain are retained." This was in fulfillment of his promise. *
