Satan does not have a sympathetic or considerate bone in his body. He doesn't back off or give one a break in times of stress or serious problems. His 'sifter' is set in motion to destroy or defame the children of God.
I doubt you are grist for his mill if you are an unfaithful, careless saved person. The non-tither, the no-time-for-the-Bible-and-prayer kind of Christian.
If you ever find yourself in the Devil's sifter, take it as a compliment. He is concerned enough about you and your life to go after you with a vengeance. Remember, the more seriously you take God and His work, the more seriously the Devil will take you.
No true Christian is fool enough to desire a few shakes in Satan's sifter. But if you find yourself there, please recall what Jesus said to Peter - "But I have prayed for thee." Grateful am I that "he ever liveth to make intercession". Though troubles and trials come from the hand of our enemy, take hope. Christ Jesus is there to deliver and sustain amidst the fiery trials.
