This life is fleeting. When we understand what that means we will regard this life as nothing in the right sense. If we turn to St Paul we can see that he had this understanding that he counted this life as Christ and to die as gain. Our whole purpose then is to live our time here on earth for God and for is glory and for others. To seek salvation solely and diligently and to remember our death daily so that we can approach our Lord in sobriety and humility.
