Why is it said that Satan desires to sift Christians like wheat?

In Luke 22:31, the phrase 'Satan hath desired to have you, that he may sift you as wheat' illustrates his aim to destroy the faith of God's people. The imagery of sifting wheat signifies shaking, scattering, and testing, aiming to separate what is valuable from what is worthless. This spiritual warfare shows that while believers are securely held by Christ, they are still targets for Satan's schemes. The encouragement is found in understanding that, like Peter, believers can withstand these attacks through the prayers of Christ. Recognizing this spiritual reality reinforces the need for vigilance and reliance on God’s strength in adversity, safeguarding our faith amid trials.
