It is a very dangerous thing for a minister to think that everything he preaches is the Gospel of Jesus Christ or that everything in his ministry may be correctly designated as “Gospel ministry.” The Gospel is a very specific message.
I used to complain that it's really difficult to be a human. But I realized that I complain because I am rebellious. Instead of acknowledging my weaknesses and praying to God, I fed my flesh and complained about temptations. But God is merciful. He humbled me.
