If you have ever lifted up a flagstone or a rock in the garden you will have noticed all the bugs and creepy crawlies scurrying for cover as you expose them to the light. Similarly, when someone comes close to God they see the light of His holiness and it shows up their own sinfulness and unworthiness. That’s why we need to come into the light; we need to confess our sin and not scurry away and hide from God. When we confess and repent of our sins the blood of Jesus cleanses us and we are forgiven and able to bathe again in the light of God’s holiness.
