House Built on a Rock

In Jesus' parable of the two houses we see nothing of the houses that differs but their foundations, which are unseen. But what does it mean to have a house built on sand? Of sand it was said that Abraham's descendants would be as the sand of the seashore. So to build one's house, or church, on sand would be to base it on the people rather than on Christ who is the Rock. The foundation of the church cannot be  the thoughts, desires, wishes, or dreams of the people, giving them what their ears are itching to hear. It must be the word and confession of Christ, for so he named Peter when he confessed him. What we need is not a church built upon ourselves, but one thing only: the word of the Gospel of Christ, for this is what he taught. And this is what he gives. Sermon for Midweek of Trinity VIII.
