How do we know God has a purpose in our suffering?

According to the sermon, everything that God does is directed towards the redemption of His chosen ones. This includes the difficulties and sufferings we endure. The preacher emphasizes that even in our pain, God is actively working for our ultimate good and redemption. Romans 8:28 tells us that 'all things work together for good to them that love God,' which affirms that our sufferings are under God's sovereign control and serve His purpose. The belief that 'everything God does, He does for the redemption of His people' anchors our understanding of suffering, giving it meaning and direction in light of God's redemptive plan.
