Scripture consistently and strongly warns against drunkenness and the dangers wine and strong drink bring, and even commends avoiding alcohol altogether as the wisest path. Because the body is a temple of the Holy Spirit meant to stay clear-headed for prayer, service, and self-control, abstaining entirely is the safest and most consistent application of these principles.
Proverbs vividly warns against the sorrow, danger, and deception that come with strong drink, going so far as to counsel not even looking at wine when it sparkles in the cup. Priests were forbidden from drinking before entering the tabernacle so their judgment and service to God would stay clear, and Ephesians commands believers not to be drunk with wine, contrasting it with being filled with the Spirit. Since the body belongs to God as a temple of the Holy Spirit, and since alcohol can cloud judgment, harm health, and lead others into destructive habits, choosing total abstinence honors both the clear biblical warnings against drunkenness and the broader call to full self-control, a clear mind, and a body kept fit for God's service.
Discipleship applies the gospel to the whole life: body, mind, relationships, work, finances, and worship. Healthy choices and faithful habits do not earn salvation; they are grateful stewardship of the life God has entrusted to us and practical ways to serve others.
