And when He saw the crowds, He went up to the mountain. And after He sat down, His disciples came to Him.
The new King called His followers by the seashore, but He went up into the mountain to give them the constitution of the kingdom of the heavens. This indicates that we need to go higher with Him for the realization of the kingdom of the heavens.
It is very meaningful that the constitution of the kingdom of the heavens was decreed upon a mountain. The sea signifies the Satan-corrupted world. When we were caught by the Lord, we were in the Satan-corrupted world endeavoring to make a living. But after the Lord caught us, He led us up to a high mountain signifying the kingdom of the heavens. This indicates that the kingdom of the heavens was not established on the seashore, but on the mountain.
