Sand castles are beautiful things. They take our minds away to faraway places with ideals of princes and dragons and lords and battles. To make sandcastles well, they take a lot of sand a lot of water and a lot of patience and a lot of talent.
But, we all know that every sandcastle, no matter how intricate and beautiful, will eventually find itself beaten down by the wind and the rain and will soon be a pile of sand again, some of it being swept back into the sea.
The Bible says that we are like sandcastles. We too are wasting away. The older you get, the more pains you will have and the slower you will move. Eventually, you will return to the earth. God said, “You are dust, and to dust you shall return” (Genesis 3:19).
Yet, for believers in Christ, we have reason not to lose heart at this reality of life, because God is working inside of us to produce something that will last for eternity. Paul explains, “Therefore we do not lose heart, but though our outer man is decaying, yet our inner man is being renewed day by day” (2 Corinthians 4:16).
