Why am I here? Is there a purpose to life? Questions we all need to ask. I think I have often ignored these questions as being too mystical or only for those whose lives are messed up or without direction.
But until we can honestly address this question in our own life, I fear that we as Christians risk stumbling through this life being motivated by the latest fad, cause or calling (Christian or otherwise) that comes our way. For the unsaved, they arrive at the end of their days on this earth having accomplished great things or accomplishing little, but still missing the real purpose for their existence, and thus going into eternity suffering the greatest loss imaginable - eternally suffering the absolute absence of Love.
