Isaiah 26:1-6; Psalm 118:19-24; Matthew 7:31-27
In Hebrew scripture, the authors of the Jewish Wisdom books frequently contrast two Ways – the way of good and the way of evil, or the way of meaning and the way of vanity. A consistent theme ascribed to the way of holiness, integrity, and truth is its weight. This way has substance – it is heavy, solid, and stable. Those who follow this way have roots, as in Psalm 1: “They are like trees, planted by streams of water, with leaves that do not wither.” By contrast, the way of evil or vanity is light, ephemeral and insubstantial. Those who follow it become like chaff which the wind blows away, like dew or clouds that evaporate, like grass which withers in the sun, or like the web of a spider brushed casually aside.
Jesus’ parable of the two house-builders, which concludes the sermon on the mount in Matthew, participates in this tradition of the Two Ways with its stark opposites: the wise man and the foolish man, the immovable house built on rock and the flimsy house built on shifting sand. This is is a sobering reminder that authentic discipleship demands the concentrated weight of commitment expressed in actions. Accepting wise and prudent commitments is a practice that gives our life with God substance.
