Jesus ended his Sermon on the Mount comparing two different foundations. There were two different builders. One builder was foolish and the other builder was wise. There were two different foundations. One house was built on sand and the other house was built on the rock.
All foundations will soon be tested by reality. The house built on the sand will collapse. However, the house built on the rock will not fall. Jesus concluded his Sermon on the Mount this way on purpose. His purpose is to get more and more people to trust in him. "Therefore, everyone who hears these words of mine and puts them into practice is like a wise man who built his house on the rock" (Matthew 7:24). Please pray for God's wise building project of salvation to spread to more and more people.
