Does it glorify God and does it edify His people (me included)?
Whether therefore ye eat, or drink, or whatsoever ye do, do all to the glory of God. (I Corinthians 10:31)
Since we were created in His image and after His likeness for His pleasure, there is not one area of our lives that ought not to be submitted to His Word and carried out for His glory. Notice how it extends even to eating and drinking.
Let us therefore follow after the things which make for peace, and things wherewith one may edify another. (Romans 14:19)
Christian liberty is a favorite topic today behind which many people hide all sorts of activities and lusts that can actually be judged according to the Scriptures. It's interesting to note that Paul's conclusion in areas of liberty was that if the liberty caused someone else to stumble, the liberty was not to be exercised (I Cor. 8:9-13). Lest you think that this was unique to Paul, consider the words also of Peter, who exhorted believers to stand fast in the face of societal pressure and persecution, As free, and not using your liberty for a cloke of maliciousness, but as the servants of God. (I Pet. 2:15-16)
