"Come to me, all you who are weary and burdened, and I will give you rest." Mat 11:28
Jesus asked us to move in His direction when we are feeling tired. I've talked to many people lately that just seem worn out. It seems we get so involved with stuff that we often hurt the stuff that really matters. In our busy-ness we damage our business.
I think that Jesus' definition of rest is not to "cease activity" but rather to do His activity rather than yours. It's an exchange of that stuff. When you are involved in the right things, it does not feel laborious at all. Consider this: you may not need a vacation, you may need another job!
If you are weary and overwhelmed, if you are tired and wrung out by life, move closer to the Lord. Your hope and help can be found in Christ. Just don't be looking for that rest He provides to always be a break. It may just be a breakout in a new direction!
