In the first reading the prophet Isaiah assures that God will protect and grant peace to those who trust in him: “You keep in perfect peace the one of steadfast mind, the one who trusts in you. Trust in Yahweh forever for Yahweh is an everlasting Rock.”
The Gospel reading which is the conclusion of the Sermon on the Mount in the Gospel of Matthew makes use of a similar image of a rock as foundation stone in describing Jesus’ faithful follower: “Anyone who hears these words of mine and acts accordingly is like a wise man who built his house on rock.”
If our spiritual life with God is built on solid foundation like the big tree trunk for the tree house or solid rock for our house, our spiritual life will be sturdy and strong. What does this mean for me and my spiritual life?
The faith we received handed on to us at our baptism must be nourished in our lives for it to grow, by prayer and the sacraments, listening and reading God’s word and listening to commentaries on God’s word and spiritual and corporal acts of mercy and love. These make our faith strong, even in the midst of doubt, temptations and trials. Indeed “not everyone who says to me: Lord! Lord! will enter the kingdom of heaven, but the one who does the will of my heavenly Father.” To enter the kingdom of heaven, we must do God’s will.
