Each of us in life is going to face crumbling walls. Illness, death, disability, discord, disobedience, and desertion just to name a few. How do we make sense of this?
If we look at our lives as houses, each of these houses is made of different materials: beliefs, experiences, people, perspectives. When the storms of life prevail against our house, the degree to which our house weathers the storm is based on the materials it is formed of. A house on a firm foundation stands while a house on say, sand, collapses. A hut made of branches is quickly destroyed while a house made of rock withstands pounding wind and rain.
This is precisely the metaphor Jesus uses in the New Testament book Matthew 7:
The testimonies here are of individuals who believe there is a God who created the world. A God we as humans chose to disobey and distrust thus severing our relationship. This is the point where all the "bad" enters our world. But then, God sent himself in human form as Jesus Christ, living a sinless life and sacrificing himself as the perfect restitution for our wrong. And a God who has promised to redeem us both now through the processes of renewing us with his Holy Spirit and fully one day when He returns to bring an end to sin. All of this can be found in the Bible.
19So then you are no longer strangers and aliens, but you are fellow citizens with the saints, and are of God’s household, 20having been built on the foundation of the apostles and prophets, Christ Jesus Himself being the corner stone, 21in whom the whole building, being fitted together, is growing into a holy temple in the Lord, 22in whom you also are being built together into a dwelling of God in the Spirit.
