Consuming caffeine is not directly mentioned in the Bible. However, there are some biblical principles that can apply when discussing whether caffeine addiction is a sin.
Caffeine addiction – Is it a sin?
First, 1 Corinthians 6:12-13 teaches, "'All things are lawful for me,' but not all things are helpful. 'All things are lawful for me,' but I will not be dominated by anything. 'Food is meant for the stomach and the stomach for food'—and God will destroy both one and the other." In other words, the stomach was made for food, but that does not mean we are to treat it however we wish. Our goal is to serve God in every area of life, including in what we consume. A person can choose to consume coffee, tea, soft drinks, or energy drinks, but should also consider if there is a point at which caffeine is addictive or harmful to one's body. Many studies have shown both health benefits and concerns with caffeine. In limited amounts, caffeine can help improve stamina and energy. In large amounts, caffeine can become addictive, cause headaches, and even contribute to heart problems. Moderation has been recommended by health experts as best to avoid such problems.
Second, a believer in Christ must also ask if caffeine consumption is hindering one's service to God. For example, a cup of coffee might not be a problem, but ten cups a day might be causing a person to live in unhealthy ways that hurt one's relationship with God and service to others.
Third, ask yourself whether your caffeine consumption is good stewardship in the eyes of God. In other words, an occasional latte or mocha might not be a problem, but is the amount of money you are spending on caffeinated beverages hurting your ability to honor God with your finances? Your level of caffeine in this case may not be sinful, but perhaps your spending or stewardship in this area is.
Fourth, ask if your caffeine addiction is being used as a substitute for honoring God with your body. In other words, do you drink an energy drink each day because you fail to honor God through a lifestyle that includes adequate rest? For some people, the godliest decision you could make is to get a good night's sleep. However, this also interacts with other life issues, such as your work schedule, what you watch on television at night, or other factors that may need to be reconsidered.
In summary, caffeine can be taken in moderation without sinning against God. However, an unhealthy addiction to caffeine may have several negative effects. These can include negative health problems, not honoring God with your body, negatively impacting service to others, and the possibility of poor financial stewardship. Each person should evaluate his or her own practices in this area and seek change as necessary to honor God with their body, services, and resources.
