I have a brother in Christ who has struggled with alcohol. He has been responsible enough to avoid drinking and driving, but he has had occasions where he has drunk too much. He is a Christian and feels a calling to evangelism. He asked God to remove the temptation of alcohol, and has stated that he abstains for personal reasons. His wife believes it is a sin to drink, as does his local church. He has provided a strong testimony of his life, including his struggle with alcohol. Now he has rationalized his drinking by determining that it is not a sin. I agree with him in principle…alcohol itself is not a sin. But he has already wrestled with this issue…I worry about his testimony and his future wellbeing. What advice would you give my brother?
