Be strong and immovable. Always work enthusiastically for the Lord, for you know that nothing you do for the Lord is ever useless.
1 Corinthians 15:58
Let this necklace be a reminder that what you do matters. God uses you in ways you don't even know. Stand firm in that truth. If you set out to be a light, to make a difference, God will use you. The enemy will tell you any lie he can to keep you from doing things that make a difference. Even just those little things that you may think are pointless, they are not. They matter, so stand firm and keep on. Nothing you do for the Lord is useless.
