How you handle this life is a reflection of how you will handle the eternal life to come. If you are beaten, tormented, frightened, and lost, then your hope is not in Christ. You are not accepting the gift of salvation that God provided for you. You are allowing the enemy a victory he has no right to. There is no addiction that your will cannot overcome. It may take time, it may take a few or many setbacks, you may have to do it without family and friends who have long since given up, but you can overcome anything through Christ.
