1. Heaven and earth will pass away, but my words won't (28-31)

As people knew that summer was near through observing the fig tree, so Jesus explained about signs in advance that we may know that the end of the age is near. People will laugh saying, "Where is this 'coming' he promised? Everything goes on as it is has since the creation!"(2 Pet 3:4) But as Jesus confirmed, heaven and earth will pass away, but Jesus' words will never pass away!"

2. Keep watch (32-37)

We should especially keep watch, be awakened for no one knows that day, not even the angel, nor the Son, but only the Father. People will either be paralyzed in panic or live a pleasure-seeking life saying, "Let us eat and drink for tomorrow we die." (Isa 22:13) But we, his elects must live guarding our hearts with Jesus' peace, carrying out his Great Commission. We should remember Jesus' word: a master goes away leaving his house and puts his servants in charge, each with his assigned task till he would come back anytime. (Mt 24:45)
