What we do with God is the most important thing we will ever do in life. There is more to "life" that the few years we have here on earth. This time on earth is just the "blink of an eye" in the perspective of eternity. So, how I see and understand God and His plan for those he has created has drastic implications for now and eternity. If I understand that God has a plan for my life and has my best interests at heart I will submit to His guidance; which is mainly through the Bible, his communication with us. That guidance teaches me how to live life well and that in turn affects everyone that I come into contact with, either for their benefit or detriment.
