For we are His workmanship, created in Christ Jesus for good works, which God prepared beforehand that we should walk in them.
Ephesians 2:10 (NKJV)
No matter where we may find ourselves or what our past may have looked like, God has created us for good works. Our task is to look to Jesus, and to trust what He has put in our hearts. As we remain faithful, as we trust Him, we will find ourselves led into opportunities to shine His light and to serve in exactly the way God has purposed it for us.
