" First importance. The Bible tells us that, while there are many different callings and many possible areas of service in the kingdom of God, one transcendent truth should define our lives. One simple truth should motivate our work and affect every part of who we are.
Christ died for our sins.
If there's anything in life that we should be passionate about, it's the gospel. And I don't mean passionate only about sharing it with others. I mean passionate in thinking about it, dwelling on it, rejoicing in it, allowing it to color the way we look at the world. Only one thing can be of first importance to each of us. And only the gospel ought to be. "
