I often wonder this myself. The main reason I'm still here (by my choice) is because I know God has (a) reason/s for keeping me here and I can't wait to see what the reason/s might be (that and I'm convinced there is a Hell and I just can't take the chance that suicide may be unforgivable). If staying here means bringing someone to the kingdom of heaven, then praise be!--more friends to celebrate with me when the party starts.
