In Luke 14, Jesus taught, "When you are invited by someone to a wedding banquet, do not recline at table in the place of honor. A more distinguished guest than you may have been invited by him, and the host who invited both of you may approach and say, 'Give your place to this man,' and then you would proceed with embarrassment to take the lowest place. Rather, when you are invited, go and take the lowest place so that when the host comes to you he may say, 'My friend, move up to a higher position.' Then you will enjoy the esteem of your companions at the table."
We can apply this lesson to our expectations in life. To avoid disappointment, it's better not to expect happiness in this world because things can go bad at any time. But we can certainly expect great happiness in the next world if we remain faithful.
