Work is a gift, part of a perfect world. It's humans who messed it up and caused toil to enter the picture.
Conversely, part of God's plan to redeem humanity and all of creation includes fulfilling, enjoyable work.
Take inventory. What is work for you? I'm not saying you'll be able to avoid stress completely, but I am saying God intends for work to be beautiful. Invite Him into your paradigm of "work". Invite Him to redeem and restore it — even in ways you don't realize you need it.
