Did you know that a chicken egg can be unrefrigerated for 2 months without going bad? Wait, you say, why do grocery stores waste electricity on refrigeration for eggs? Ah, you see, grocery store eggs are pressure washed to reduce the chance of bacteria. In the process, the shell is weakened. Once your shell is weakened, the entire contents can deteriorate more quickly. If the skin is broken, there is a chance of infection. God made us and the egg to be whole and intact.
What does it mean to be spiritually whole and intact? It is holiness.
Make every effort to live in peace with everyone and to be holy; without holiness no one will see the Lord.
2 Corinthians 7:1
Therefore, since we have these promises, dear friends, let us purify ourselves from everything that contaminates body and spirit, perfecting holiness out of reverence for God.
What breaks us? Sin.
For the wages of sin is death, but the gift of God is eternal life in Christ Jesus our Lord.
The solution for our sin? A sacrifice by the one who is whole and without blemish.
1 Peter 1:8
8 For you know that it was not with perishable things such as silver or gold that you were redeemed from the empty way of life handed down to you from your ancestors, 19 but with the precious blood of Christ, a lamb without blemish or defect.
Such a small, microscopic opening can begin the decay process. So, we, too, must be vigilant.
