Polishing the mirror on a giant telescope is a complex process. Removing imperfections from the surface is necessary to achieve a clear image. If one of these telescope mirrors was the size of the United States, the tallest “mountain” on the surface would be less than one inch tall.¹ The more imperfections removed, the purer the reflection of the heavens will be.

There is also a connection between purity and “seeing” God. Since no one has “seen” God (John 1:18; 1 John 4:12), what did Jesus mean when He said that “the pure in heart . . . shall see God”? Ultimately, believers will see the Lord in His presence (Revelation 22:4), but for now Jesus’ words must be interpreted spiritually. The apostle John wrote that “he who does evil has not seen God” (3 John 11). Meaning the evildoer has not recognized God in His worthiness and righteousness. Just as the imperfections in a telescopic mirror can blur the vision of the heavens, so the imperfections of the heart can blur a true vision of God.

Purpose daily to live with “clean hands and a pure heart” in order to see God and enjoy His presence (Psalm 24:4). 

The pure heart is God’s paradise where He delights to walk.
