The rich man ran to Jesus seeking answers. He had lived life purposefully and with intention. He still lacked rest. 
Jesus told him, “sell what you have and follow me”. 
The young man walked away saddened, still missing the rest he sought after…not because Jesus hid it from him, but because he wasn’t willing to do what was necessary to obtain it. 
Going to Jesus for answers is great but not living by them won’t help you any. To have rest we need to remember that we aren’t the ones that should have authority over our lives. The authority should be reserved for Jesus…meaning rest comes when we choose his will over our own.
