The Lord has recently been showing me that spending too much time praying out of worry is like having a hole in your watering can: when you go to apply soaking faith, you have little to none left, so nothing comes of your requests.
The secret to stong faith is focusing on Jesus, the problem-solver, instead of on the problem itself. Seeking the will of God, then, is essential to mountain-moving prayers. It's Christ's plan that will work, not yours.
Put it this way: when we try to figure out the solution, the result is worry. But when we leave the path-finding up to Jesus, the result is simply following Him to relief, resolve, and breakthrough.
Down with futile imagination,
Up with fruitful trust!
