As I sat in church, I noticed that no one could see in, and I could not see out through the stained glass windows. When we accept Christ into our lives, the sin-stained window of our heart is cleaned. His light can shine in, and you can see Him clearly, that glorifies Him. What joy that brings to your heart.

Wash me thoroughly from my iniquity, And cleanse me from my sin. Psalm 51:2 NKJV
