He will not grow faint or be crushed until he has established
justice in the earth. Isaiah 42.4
Apparently St. Francis Xavier struggled to learn languages, and yet this did not stop him from being one of the most active and widely travelled missionaries in the history of the church. For anyone who has struggled to make themselves understood in a foreign language, this is incredibly encouraging! What he understood most of all is that the gospel is for the poor, the disenfranchised, for those the world does not care about.
Even when you can't say a word, you can be that gospel presence in someone's life!
