How do we know God performs all things for good?

Romans 8:28 provides a profound assurance that all events in a believer's life are orchestrated by God for their ultimate good. This does not eliminate pain or suffering, but it calls believers to trust in God's sovereign purpose. The assurance comes from knowing that everything, even calamities, is used by God to further His plan for salvation and ultimately glorify Himself. In Christ, we find comfort in the reality that every circumstance contributes to the believer's spiritual growth and conforms them to the image of Christ.
