Why/How do you share the gospel with your friends?

There are many reasons why I share the gospel with my friends. Imagine that you have an unlimited supply of icecream that is healthy for you, it's flavor is dependant on the person who is eating it, and everytime you ate some you felt like a million dollars. Wouldn't you want to be able to share that with everyone around you. That icecream is what the gospel is for all who are willing to try it. I've seen the gospel bless my life in every way. It has strengthened my family relationships. It has helped me concentrate and get good grades in school. I has helped me develope a strong work ethic to be able to hold a job. It has helped me make the right decission during hard times and has kept me out of major trouble. It has increased my joy in helping other people around me. It has given me a knowledge of what happens to loved ones that have passed on that has helped me to be able to overcome the sadness of their loss. It has helped me to be a more Christlike person and many more things. I want to be able to see other people have these blessings in their lives.
It is also a commandment that we share this message with everyone. Our Father in Heaven wants to bless the lives of all of his children. He can only do so when they are on the right path, and they can only be on the right path if they know which path is right. God uses us to show that path to others, but can only do so if we are willing to do his will.
Right now I am sharing the gospel by serving a full time mission in the Portland, Oregon area. It has been a major blessing to be able to help others change their lives for the better. That alone has added to my desire to share with all of Gods children.
