Consuming caffeine and caffeine addiction are not specifically mentioned in the Bible; however, there are principles to help us with this topic. Our goal is to serve God in every area of life, including in what we consume (1 Corinthians 10:31). 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. The Bible warns us not to be mastered by anything (1 Corinthians 6:12). While coffee or caffeine may be enjoyed for its other benefits, when we start requiring caffeine to function or be pleasant, we should question if we have allowed it to master us.
Although enjoying an occasional latte or mocha or soda is not inherently sinful, we should view our consumption considering a few things. First, is consuming being used as a substitute for honoring God with our body? Do we drink an energy drink each day because we fail to honor God through a lifestyle that includes adequate rest? God calls us to come to Him for rest (Matthew 11:28). He helps us sleep (Psalm 4:8). For some people, the godliest decision we could make is to get a good night's sleep, not grab another cup of coffee. Second, we need to evaluate how we behave when we have caffeine and when we do not. We cannot rely on caffeine to give us energy or a good attitude. God calls us to exhibit the fruit of the Spirit in our lives (Galatians 5:22–23). Relying on caffeine to help us be kind is a misplacement of trust and a misplacement in the source of our strength to live for God. Caffeine is not the Holy Spirit, and while caffeine is occasionally necessary to perk us up, we should be concerned at a level of addiction that requires coffee to speak kindly or to think clearly. If there are underlying health issues, we should take care of those, and we should seek the Holy Spirit’s strength to live for Him. We also need to ask ourselves whether our caffeine consumption is good stewardship in the eyes of God. Is the amount of money we spend on caffeinated beverages keeping us from being generous to others or honoring God with our finances? Our level of caffeine in this case may not be sinful, but perhaps our spending or stewardship in this area is. Each person should evaluate his or her own practices in this area and seek change as necessary to honor God with their body, attitudes, and resources.
