What does sifting mean in a biblical context?

To sift, as referenced in Luke 22:31, is to separate the wheat from the chaff, illustrating how God allows trials to refine His people. This metaphor signifies that the challenges believers face are not without purpose; they serve to strengthen and reveal the genuineness of their faith. As Peter states in his epistle, the trial of faith is precious, more valuable than gold (1 Peter 1:6-7). Through sifting, believers can grow in their reliance on God, emerge stronger, and be equipped to encourage others in their faith.
