One of the defining features of our current postmodern world is an increase in selfishness, a rise that has resulted from the lack of a controlling belief system. With nothing larger than oneself to believe in, our natural tendency will be to act, think, and speak in ways that serve ourselves. The Bible describes this desire as the primal problem of the human situation – the centering of ourselves over against all others; fundamentally, the desire to be God.
The solution to this problem is to A) realize that happiness lies in the happiness of others and B) finding the fuel to be selfless in the one truly selfless act in the history of the universe – Jesus willingly giving up his life to save our lives.
