Sometimes people hurt us and we end up deeply shaken. 
But those people also accomplish something else. They reveal to us what is in our hearts. I don’t often like what I find in mine: anger, fear, pride… I even contemplate revenge.
Someone in the Bible suffered injustice as well, yet he reacted differently. He cried out, “My soul finds rest in God alone… He alone is my rock and my salvation. He is my fortress. I will never be shaken.” (Psalm 62:1-2)
Can anything good come out of pain? There is one thing. Through it God can show us if we have wandered away from him. Through it we can make the choice to return and find rest in him.
