Are you living a sustainable life? Maybe we've caught ourself saying things like, "I can't do this much longer. I just can't keep this up forever." When we make comments like these, what we're really saying is, "I know I have limits and that I've reached them, but I'm going to ignore them and see how long I can get by with it."
Our body gives us warnings when we're pushing too hard, like an ache here or a pain there. But we think, "I'll be all right," and we ignore the warnings until we're too sick to ignore them.

I'm not proud of this, but for the first twenty years of my life, I felt physically terrible a lot of the time. I ran to doctors and tried all kinds of medicine. The doctors tried to tell me that I was simply pushing myself too hard, but I ignored them. I kept pushing myself to do all and simply exhausting myself. Finally, I realized that we can't ignore God's direction to take time to rest and not pay a price for it. So I made some changes.

If we are living an unsustainable life, stop putting off making the changes we need to make. Don't wait until something happens, like a nervous breakdown or a heart problem. Make changes now to live the kind of life God wants us to live. When we live God's way, We can guarantee we'll discover an overwhelming new level of peace in our life.
He makes me lie down in [fresh, tender] green pastures; He leads me beside the still and restful waters. (Psalm 23:2 AMP)
