Forgiven so I can Forgive?

My first question is this; why did Jesus come to earth? I think that there are several answers and all would be partially correct. I think he came down as a guide. Some one to show us the way. How to live the best life. He also came to pay the price of our sin. Not to forgive us. You see God has already done that. By sending his son he shows that he already has. The next question is this; if you have forgiven someone do they have to ask in order for you to have forgiven them? I don't think so. When I ask someone to forgive me it's because I want to know if they have. Forgiveness is basically the same as grace. They mess up and you say it's ok knowing that they haven't changed and will do it again. But what God wants is repentance. And Jesus shows us what that looks like. We don't have to get it perfect because we are forgiven and have accepted that. But In all this the lord has saved us from death which we know was the consequence of our actions and if with this knowledge we do not aspire to become a better person then we truly are no better than sinners.
