Mark 13:28–31 makes a lesson about recognizing the end times using an example from farming. Although no one can know when Jesus will return (Acts 1:6–7), God promises to give us signs to let us know the end times are approaching. More specifically, He has told us the sign of the beginning of the tribulation and how long the tribulation will last. If we pay attention, these signs will be as easy to read as the seasons’ effects on a fig tree. Many words have been written over verse 30, but it merely means that the tribulation will be short. Matthew 24:32–35 and Luke 21:28–33 record nearly identical accounts.
