20:20 his side. The wounds of the crucifixion will always remain in His body, even though it is now not subject to pain or death. Likewise, our own resurrection bodies will still be recognizable (note Philippians 3:21).
20:20 saw the Lord. Some others had already seen Him by now, in addition to Mary Magdalene. These included the women (Matthew 28:9), Peter (I Corinthians 15:5), and the two disciples on the way to Emmaus (Luke 24:13-35).
20:21 so send I you. This is the first outline of Christ’s great commission to evangelize the world. It was later amplified further, probably in the following order: Matthew 28:18-20; Luke 24:46-49; Mark 16:15-16; Acts 1:4-8.
20:22 the Holy Ghost. Breathing on them was a symbolic act. As in the Old Testament, the Holy Spirit could already have come on the disciples for specific ministries, but Christ had promised He would soon indwell them permanently (John 14:16-17). The command now to “receive ye the Holy Spirit” is imperative and must be carried out at the proper time. However, Christ also told them to tarry in Jerusalem until then (Luke 24:49; Acts 1:4,8). The promise was fulfilled on the day of Pentecost (Acts 2:1-4).
20:23 remitted unto them. Only Christ can remit sins, and He does so on the basis of saving faith in Himself. The disciples, however, were given authority to recognize such faith, and then to give assurance to new believers. The authorization, as evident from the tenses in the Greek, should actually read: “Whose soever sins ye remit, they shall have been remitted unto them.”
