As humans we are inclined to doing everything we do in order to benefit ourselves in this life however we should also consider the life in the hereafter. Live as if you will live together because everything you do will affect today, tomorrow, and eternity!
“If you doubt the existence of a hereafter, consider this: The baby in the womb has eyes with which it cannot see; a mouth through which it cannot eat; and lungs with which it cannot breathe. It is clear, then, that eyes, mouth and lungs were created not for the world of the womb, but for the world outside the womb. Similarly, we in this world have imaginations that can embrace infinity; we have desires that reach out to eternity; and we have needs that are truly never-ending. It is clear, then, that imaginations, desires and needs were not created for this world alone, but mainly for the world which is yet to come…”
