We should never lower our expectations for life. Our God is great and we should have a great expectancy for what is going to happen.
Maybe you are in a season of life where it is hard for you to be optimistic. Maybe a marriage has failed, a relationship ended, maybe finances seem to be getting tighter and tighter, well let me encourage you.
If you are a follower of Christ, if you put your trust in God, your best days are ahead of you not behind you. You were created to be the victor not the victim. God loves you and when He looks at you He sees a champion. He sees potential in you to do greater things.
