Last December, my family and I went to the mountains. We had lived in a tropical climate all our lives, so it was the first time we could see snow in all its magnificence. As we contemplated the white mantle covering the fields, my husband quoted Isaiah, “Though your sins are like scarlet, they shall be as white as snow” (Isaiah 1:18).

After asking about the meaning of scarlet, our three-year-old daughter asked, “Is the color red bad?” She knows sins are things God dislikes, but this verse is not talking about colors. The prophet was describing the bright red dye obtained from the eggs of a small insect. Clothes would be double-dyed in this bright red so the color became fixed. Neither rain nor washing would remove it. Sin is like that. No human effort can take it away. It’s rooted in the heart.

Only God can cleanse a heart from sin. And as we looked at the mountains, we admired the pure whiteness that scrubbing and bleaching a piece of cloth dyed in scarlet red can’t achieve. When we follow Peter’s teaching, “Repent, then, and turn to God, so that your sins may be wiped out” (Acts 3:19), God forgives us and gives us a new life. Only through Jesus’s sacrifice can we receive what no one else can give—a pure heart. What a wonderful gift!
