21 他们在那城里传福音，使许多人作了门徒，然后回到路司得、以哥念、安提阿， 22 坚固门徒的心，劝他们恒守所信的道，又说：“我们进入上帝的国，必须经历许多苦难。”
21 They preached the gospel in that city and won a large number of disciples. Then they returned to Lystra, Iconium and Antioch, 22 strengthening the disciples and encouraging them to remain true to the faith. “We must go through many hardships to enter the kingdom of God,” they said.
Encouraging is the principal way to confirm; by encouraging the disciples who had already embraced the Gospel and professed it, they urged them to make progress. We are far from being as ready and active as we should be, and so our laziness needs spurs, and our coldness must be warmed.
Let us remember, then, first of all, that we are required to suffer many tribulations; but let us also remember to add in mitigation that by them we are brought to the kingdom of God. It is just silly to say that patience is something that merits eternal salvation, for this passage is not dealing with the cause of salvation but with the way God treats his people in this world.
