We live in a world that is full of broken people. Sin has broken them and they do not function quite the way God designed them to function. They are broken.
We as Christians were once broken as well but we are no longer broken. We are "born again" and made whole through Christ. We who have experienced salvation have the responsibility to freely share our knowledge and experience with those who are broken so that they too may be "repaired" and function the way God designed them. Are we sharing our knowledge with others or are we keeping it to ourselves?
