Jesus said that those who listen to him and acted on his word were like those who built their house on a firm foundation. While the foundation of a real house might be difficult to fix, the Good News is that we can strengthen the foundations of our faith every day by simply living out our faith. Thus we need not worry about our lack of faith or what might come if we simply live each day according to our faith.
Based on Matthew 7:21, 24-27
Jesus said to his disciples, ‘Not everyone who says to me, “Lord, Lord”, will enter the kingdom of heaven, but only one who does the will of my Father in heaven.
‘Everyone then who hears these words of mine and acts on them will be like a wise man who built his house on rock. The rain fell, the floods came, and the winds blew and beat on that house, but it did not fall, because it had been founded on rock. And everyone who hears these words of mine and does not act on them will be like a foolish man who built his house on sand. The rain fell, and the floods came, and the winds blew and beat against that house, and it fell—and great was its fall!’
