Jesus cuts the will with an incisive question near the end of His sermon. As Luke recorded it, Jesus said, “Why do you call me ‘Lord, Lord’ and do not do what I tell you?” (6:46) He follows the question with the famous illustration, and favorite kids’ song, about the foolish man who built his house upon the sand and the wise man who built on the rock. The foundation matters.
What is the foundation in the story? It is not Jesus Himself, though that is true when we sing “The Church’s one foundation is Jesus Christ her Lord.” It is not Jesus’ word, though that also is true when we sing “How firm a foundation ye saints of the Lord is laid for your faith in His excellent word.” The foundation in Jesus’ illustration is obedience. One comes to Jesus, hears His words and does them. Another hears and does not do them. Disobedience is sand. Obedience is rock.
We usually emphasize the foolish man and his destruction. When the stream breaks the ruin and fall of his house is great. We observe the fool to avoid becoming foolish. That’s why Jesus Himself wonders why a man would call Him Lord and not obey. But let us also remember the blessing. When the flood comes and the stream breaks the house of the obedient cannot be shaken.
God promises great things to those who hear and do His word. Are you hungry for that blessing? Are you building so your house will stand, that is, so your life will remain upright? If not, confess it. That’s laying solid footings for a firm foundation of obedience.
