What you feed your heart on, not only affects your attitude but also your expectation for life. If I feed myself on what God hasn't done, it creates a place for offense and unbelief.
The promises of the Lord reveal His heart. The Lord has given us a process of co-laboring by which if we pray, He intervenes. The Scriptures about the last days warnings are not a promise from God, but a description of the world you are assigned to affect and change.
Everything God warns about, He gives instruction of how to overcome. Will you stand on behalf of people who don't deserve grace just as you didn't deserve grace?
