"We give great honor to those who endure under suffering. For instance, you know about Job, a man of great endurance. You can see how the Lord was kind to him in the end, for the Lord is full of tenderness and mercy." James 5:11
There are incredible stories of persecuted Christians who have endured in countries where torture and mistreatment of believers take place. Why did they have affliction? Because of knowing and proclaiming Christ. Persecution can clearly be mean, vicious, pain inflicting and even result in loss of life. Endurance is important. There is a statement of courage and confidence that is made when one endures. And when a believer endures, he or she is reminded of the endurance that Jesus had. Thank you Jesus.
When I am suffering from unjust treatment, I pray the prayer written by American theologian Reinhold Niebuhr - "God grant me the serenity to accept the things I cannot change, the courage to change the things I can, and the wisdom to know the difference." This simple prayer comforts me and reminds me of what Moses told the people of Israel, "Don't be afraid. Just stand still and watch the Lord rescue you today...The Lord Himself will fight for you. Just stay calm." (Exodus 14:13-14)
There also hope that comes from God as we endure. First Peter 2:19 says it well, "God is so pleased when, conscious of His will, we patiently endure unjust treatment."
