When you face an impossibility, leave it in the hands of the Specialist! Refuse to calculate. Refuse to doubt. Refuse to work it out by yourself. Refuse to worry or encourage others to worry. Stand against that.
Instead, say, "Lord, I'm carrying around something I cannot handle. Because You are not only able but also willing, take this off my hands. It's impossible to me, but is as nothing with You." Persevering through the pressures of impossibilities calls for that kind of confidence.
Now, our problem is that we hold on to our problems. If your Swiss watch stops working, you don't sit down at home with a screwdriver and start working on it yourself. You take it to a specialist.
The problem is that the Lord gets all the leftovers after we try to fix things ourselves. We make all the mistakes and get things tied into granny knots, then dump it in His lap and say, "Here, Lord."
No! Right at first, say, "It's impossible; I can't handle it, Lord. Before I foul it up, it's Yours." He is able to handle it. But we don't usually give God those chances to "fix" it. We are so totally (and sinfully) confident in ourselves that we don't give God the chance to do what He is a real Specialist at doing.
If something is humanly impossible, then what in the world are we doing trying to pull it off?
