Then the semesters start flying by and you finish college with a degree that's a little more practical than maybe what you had in mind.
Your life includes somebody else now and you have new plans together, a few years later and maybe a chubby baby.
The days keep flying by and you can't even remember that person who wanted those things you thought you wanted--things that didn't involve potty training or sewing stuffed robots. Life is so much richer and more full than you imagined it would be. There are hard days of course, but those are the ones that make grace all the more obvious by contrast.
A pastor said yesterday, "The greatest gift Jesus can give you is to tear away all the dreams you have for yourself...then He overwhelms you with His grace." You are left standing with empty hands so that He can fill them, not your inflated ego or talent or career or money or carefully laid plans...because a life with Him at the center is the only one that can fill...and not just sometimes.
His dreams for you are always best.
