Acts 28:16-20, 30-31 / John 21:20-25
Generally speaking, the gospel according to John is ascribed to John the apostle, but of course there are other opinions.
It is also said that John the apostle lived to a ripe old age whereas the other apostles were martyred.
Maybe that could be a reason why the gospel according to John is so different from the other three synoptic gospels.
The other three gospels, Matthew, Mark and Luke, have more historical facts.
The gospel of John has a more theological as well as a more mystical perspective.
As he ends off his gospel account, John states that he bears testimony to Jesus and he vouches that what he has written is indeed true.
So John had a distinct mission. St. Paul was a missionary for Christ; St. Peter was a shepherd for Christ; St. John was a witness for Christ.
Where the gospel of John ends off is where our own gospel must begin.
The gospel of our lives will now have to bear witness to Christ.
It is in the gospel of our lives that the eternal truth of Christ will be passed on to the next generation of God's people.
Let us pray to the Holy Spirit who will guide us to all truth and help us bear witness to Christ.
