This is such a pivotal concept to wrap a head around. I work with youth at our church and many of them struggle with this concept...it is so easy to say the right things and know the right things...but to do them truly is a completely other level and is truly what we are to strive for. The concept that this life can be faked or simply "repented" for at the end of it all is the most foolish approach to life in my opinion. I always tell them when I hear the "I have the rest of my life to get it right"... You only get one life. You only get one chance. If you believe the Bible to be true and believe God made you and everything around you than you must realize one thing. Death can come swift and out of no where. From a car striking you in the passenger seat of your parents vehicle on your way to dinner....to an aneurysm killing you in seconds right now while you listen to me speak. So with that knowledge you would realize that you do not have the rest of your life to get it "right"...we are not guaranteed tomorrow let alone the next second in our life. So making that statement tells me just one thing, you have doubts about whether this whole God thing is 100% fact...so let's talk.
