Why should we care? What great need do we have to worry?
Many people believe that they can be 'Saved' and then they are good for the rest of forever. This is not exactly the best line of thinking. We cannot 'Be Saved' in this life. It is possible to 'fall' even after being Baptized, or accepting Christ.
We should take major precations with our choices in life. As today is the Fourth of July, and most Americans will be celebrating the Day of our Independance, which usually includes Fireworks.
As a missionary I am held to particular rules that are for personal safety, which I am not held to outside of the Two Years that I wear a Name Tag. One of those rules is to not handle fireworks. some people think that this is ridiculous, and that being 22 years old 'I should be able to do things like this safely'.
Well I have handled many fireworks before my mission, and I too am pretty sure that I can still do so safely. so "Why Should I Worry, or Care"? The point is that God, through His Prophet, has given His Divine Counsel to avoid doing so.
So if I am able to follow God's counsel for Two Years, I will have His blessings with me.
Even after we accept the Gospel of Jesus Christ, we still need to give heed to the Commandments that God has given us. We can't just sit back and think that everything will go along just fine. We must continue to repent from sin, and make things right when we do something wrong.
No one can 'Be Saved' until AFTER they are dead, and AFTER ALL of their choices have been finalized.
