1) Remember that all well doing will be rewarded
If you patiently bear something for the sake of God or your testimony for Christ, you can be assured that it will be rewarded in heaven. No good thing you did for God will go unnoticed.
2) Don't compare your life with others.
Christians cannot and should not compare their lives with others, especially un-believers. We are set apart from this world and our lives can't be in the pattern of this world.
3) Fix your eyes on Jesus and your Eternal Inheritance
When we keep looking at our circumstances, people and struggles, we lose sight of the reality that this world is temporary. This is where impatience and intolerance creeps in.
