Chapter 21 of Proverbs was a comfort to me.  It reaffirms that God cares about your heart; what you do in His name He will bless.  An encouragement was given to not make your heart cold and hard to the Lord.

The Scriptures went on to pinpoint the fact that even though we see evil people succeeding, God is going to see that evil and overcome it.  The chapter ended up with the thought that the horse is used for the battle, but God is the one who makes us victorious. Make we go forth in His name to victory!
