How do we know that suffering leads to glory according to the Bible?

According to Romans 8:17, believers are identified as God's children, and thus they inherit both suffering and glory in Christ. The assurance comes from the direct relationship between the suffering endured for the sake of righteousness and the glory that follows. Throughout Scripture, we see that trials are part of the Christian experience, drawing us closer to Jesus, who Himself suffered. This assurance transforms our perspective on suffering, signaling that it is part of a divine purpose that ultimately leads to our glorification.
