A seashell or sea shell, also known simply as a shell, is a hard, protective outer layer created by an animal that lives in the sea. The shell is part of the body of the animal. Empty seashells are often found washed up on beaches by beachcombers. The shells are empty because the animal has died and the soft parts have been eaten by another animal or have decomposed.

Put on the full armor of God, so that you can take your stand against the devil’s schemes. For our struggle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms. Therefore put on the full armor of God, so that when the day of evil comes, you may be able to stand your ground, and after you have done everything, to stand.
Ephesians 6:11-13 New International Version (NIV)
For you created my inmost being;
you knit me together in
my mother’s womb.
I praise you because I am fearfully
and wonderfully made;
your works are wonderful,
I know that full well.
Psalm 139:13-14 (NIV)
The word of the Lord came to me, saying,
“Before I formed you in the womb I knew you, before you were born I set you apart;
I appointed you as a prophet to the nations.”
Jeremiah 1:4-5 (NIV)
