I know one thing for sure. This life is not easy. I have to constantly remind what to do, what I'm here for, and who I'm doing things for. This verse is a wonderful reminder of what God wants out of Christians. It sure helps me, I pray it helps you.
"Therefore, since we are surrounded by such a great cloud of witnesses, let us throw off everything that hinders and the sin that so easily entangles. And let us run with perseverance the race marked out for us." Hebrews 12:1 (NKJV)
