There is a time for everything, and a season for every activity under heaven

To everything there is a season, and a time for every purpose under heaven. 
A time to be born, and a time to die, a time to plant, and a time to reap that which is planted.
A time to kill, and a time to heal, a time to break down, and a time to build up;
A time to weep, and a time to laugh, a time to be mourn, and a time to dance. 
A time to cast away tones, and a time to gather stones together, a time to embrace and a time to refrain from embracing.
A time to get and a time to lose; a time to keep, and a time to cast away;
A time to rend, and a time to sew; a time to keep silence and a time to speak;
A time to love, and a time to hate; a time of war, and a time of peace.   Ecclesiastes 3 1-8

How much time do we have on this planet earth?. If we assume that our productive life span is between 20 and  70, we are talking of 50 years, which translates to 16000 days. If we assume that we are sleeping for 8 hours, and working for another 8 hours, the balance available is only just 8 hours, for our personal life. Which is just 1/3rd of the day. So in this whole life, we have only about 5,500 days (1/3 of 16000), for our personal lives. It is very short. Where is time to sin?. There is no time for evil. That is the best strategy for a positive life.
