JOHN 20:19-21 SO JESUS SAID TO THEM AGAIN, ”PEACE TO YOU! AS THE FATHER HAS SENT ME, I ALSO SEND YOU

John 20:19 Then, the same day at evening, being the first day of the week, when the doors were shut where the disciples were assembled, for fear of the Jews, Jesus came and stood in the midst, and said to them, "Peace be with you." 20 When He had said this, He showed them His hands and His side. Then the disciples were glad when they saw the Lord. 21 So Jesus said to them again, "Peace to you! As the Father has sent Me, I also send you."

The seventh day of the week, the Sabbath, commemorates God's finished work of Creation (Gen. 2:1-3). The Lord's Day commemorates Christ's finished work of redemption, the 'new creation.' God the Father worked for six days and then rested. God the Son suffered on the cross for six hours and then rested. The Jewish Sabbath is associated with the Law: six days of work, and then you rest. But the Lord's Day, the first day of the week, is associated with grace: first there is faith in the living Christ, and then there will be works. We also see how our Lord transformed His disciples fear into courage. First, not only did Jesus come to them, but He reassured them. He showed them His wounded hands and side so they would know it was Him, and they would know He had risen from the grave. Lastly, Jesus gives them a new purpose. The purpose of Jesus' incarnation was the spiritual salvation of the world (1:29). That also is our purpose.
