The purpose of our trials is this. Trials grow our faith and strong faith eventually produces endurance. Pastor Mark likes to call it... staying power. He explains it like this. As you mature in your faith in God, you're in it for the long haul. He say's faith in put into action becomes real and will prove itself, which in turn proves your salvation is real. It's a spiritual litmus test. If you pass the test you come out stronger and spiritually mature, instead of weak and barely breathing. Keep in mind, all things we go through aren't necessarily good, they just work towards our good.
