Many people have negative thought patterns that have been engrained in their mind over many years. This is the opposite of believing that God is, and that He is a rewarder of those who diligently seek him. Exhorts the believer to faith-filled thinking.
God is in control of our circumstances. He cares about us and will not allow us to be tested beyond what we are able to bear. Living a life of faith is not necessarily easy but it allows God to demonstrate His power through us.
