I see God giving a person a box of crayons. The colors are vibrant and beautiful and varied. The person receiving this box chooses one color and begins working with that color only. She makes lovely art but it’s limited because everything is in the same color.
I feel like God is saying he’s proud of what you have done now it’s time to explore the other gifts he’s given you. You don’t have to give up your favorite color but see what else is in the box.
