You know, I used to work with troubled teens years ago. Most of them were on probation for various crimes. Some very serious. I tutored them because they were under suspension and I also counseled them. Actually, they opened my eyes to reality as well. The majority of them had no regard for their lives, didn't even care if they got shot in the street. I didn't know how to reach them at first.
Then one day I asked the class, "If most of you really don't care if you die, why don't you die for a good cause?" Then I explained, "Make your life count for something good and memorable. Don't have suffered for no reason. Make it count!" I told them how Jesus delivered me from a horrible abusive past and life of depression and gave me a reason to live: He led me to those very young people. I told them that if I would have killed myself, I would not be there to listen to them, to help them, to teach them, to love them. I told them, "If all the abuse I ever went through was for you, it was worth it." I truly meant that, too. My heart was so filled with love and compassion for those kids, but it was absolutely the love of Jesus Christ in me.
Anyhow, several of them softened inside and opened up in front of the whole group. I will never forget one of the toughest guys in the class cried in front of everyone and said, "I wish my dad had loved me enough to discipline me when I was out of control." That got the other kids opening up as well. They became very free in sharing their hearts.
My point is, if you want your life to count, you have to pour yourself out to others. That's why we're all here, like Willie_T said in the above post. We have to be Jesus' hands and heart in this world.
