What does the Bible say about enduring suffering as a Christian?

According to Hebrews 12, Christians are called to endure suffering as discipline from the Lord. This suffering is not punitive but rather a loving training mechanism through which God builds His children in holiness and strength. The discipline may feel painful at the moment, but it ultimately yields the peaceful fruit of righteousness to those who are trained by it. Just as earthly parents discipline their children out of love, God disciplines His elect for their good, preparing them for the glory that awaits them and teaching them the value of patience and faith amidst trials.
