The Gospel is not natural, which is what makes it so difficult?

I have hear this time and time again - the Gospel is not natural.

The Gospel is hard. It is counter cultural. It is not natural to human nature that is what makes it so difficult to live out. If it were easy then everyone would do it. 

The Gospel calls people to die to self, care for the poor, live selflessly, practice hospitality, work for reconciliation, share forgiveness, embody love. 

The more that I think about it, perhaps the Gospel is the most natural thing in the world.

Perhaps we have bought in so much to the American values - self-determination, individualism, more is better, bigger is best, mine is mine, give only for what you get out of it, consume people and resources, and personal pleasure is the point of life - that we are convinced the Gospel is not natural. 

The Gospel is not natural? Maybe not.
