Ephesians 2:10 says, "For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand, that we should walk in them."
He created each of us to work alongside Him in this thing called life. It isn't a chore. It is a delight. And He will lead you. You won't be left behind. You might feel lonely now, but you aren't being left out. He's preparing things right now. He's working behind the scenes.
You are shining for Him right where you are. Don't doubt it. His Spirit lives in you. You can't help but shine.
Sometimes life is slow. Sometimes life is fast. Sometimes life is a struggle. Sometimes life isn't. Life is full of seasons. Maybe you are in an uncomfortable season right now. Remember -- it's a season. And seasons end. This too shall pass. Please don't give up. God is using you even if you can't see it. The work will bear fruit at the right time. Sometimes that fruit takes years to develop. You are precious to Him. Oh, Dear One, Don't give up. Hold on just a little bit more. Spring is coming.
