Life is [perceived as] a series of problems: Either you are in one now, you're just coming out of one, or you're getting ready to go into another one. The reason for this is that God is more interested in your character than your comfort. God is more interested in making your life holy than He is in making your life happy. We can be reasonably happy here on earth, but that's not the goal of life. The goal is to grow in character, in Christ likeness.
