1-4: Our generation is looking for a sign too, but we receive the same sign of Jonah that they did. The resurrection!
1 Corinthians 15:3-8 “For I passed on to you as of first importance what I also received—that Christ died for our sins according to the scriptures, and that he was buried, and that he was raised on the third day according to the scriptures, and that he appeared to Cephas, then to the twelve. Then he appeared to more than five hundred of the brothers and sisters at one time, most of whom are still alive, though some have fallen asleep.Then he appeared to James, then to all the apostles. Last of all, as though to one born at the wrong time, he appeared to me also.”
5-12: The disciples are being dense again, and Jesus challenges them about it. “How could you think that I was talking about literal bread? Don’t you think based on what happened before that I could take care of that?!?!” They finally realize that he is talking to them about the false teaching of the religious leadership, and it reminds us to be on our guard as well.
13-20: The “keys” were also given to the other disciples (Matthew 18:18). By declaring the confession that Jesus is the Messiah they open the door to heaven. They forbid (bind) or allow (release) entrance based on the divine decree that only those who believe can get in (will have been bound/released in heaven). The same is true of us. We present the gospel, we provide the key to a right relationship with God, and if others believe they will be saved!
21-28: We’re reminded here that pain is a part of discipleship, and Jesus is our example. Life isn’t perfect, and we have to endure hardship. We take up our cross daily and follow Jesus. Although rebuked here, Peter learned his lesson.
1 Peter 2:21 “For to this you were called, since Christ also suffered for you, leaving an example for you to follow in his steps.”
Finally, how would some of them see Jesus coming in His kingdom? I think that it’s significant that the next thing Matthew records is the transfiguration!
