Jesus challenges his disciples not to look back, but to keep going whatever comes. To be Christian, we must find mercy and love in our hearts in the midst of trials, even if no one else respects that, for love and mercy is our call and our ultimate gift to the world.
St. Paul encourages us to "hold on to what is good," but sometimes, we get discouraged and don't know why we should even try. J.R. Tolkien gives voice to a reason.
Jesus tells us, "blessed are those who hear the word of God and observe it." This could apply to us as much as it applies to every saint, if we let it.
Jesus asks, “Why do you call me, ‘Lord, Lord,’ but not do what I command?" One reason is because we do not trust that God loves us. If you are having trouble trusting in God, maybe go to Mary and let her show you the way.
