I have lived on what I would call both sides of a Christian life. In my early days I did not follow the example He left us. Later as my heart was transformed and I felt a closer relationship with Him I was compelled to do more for others and I did so with joy. I think that is the self test. When you love Jesus you can't help, but be compelled to do what you can to help others. You are saved and you know it and you know that good deeds have nothing to do with your salvation, but you do good things even when you know you don't have to.
