在二戰時期拍攝的一張照片，給了所有人一個警示。照片呈現的是某個城鎮的納粹總部外面，一位穿著輕便的女子正在過馬路；一位西裝革履的男子走在人行道上；一位男子正看著大樓轉角的告示牌。似乎沒有人注意到，在總部大門上方，懸掛著幾乎佔建築物一半大的巨型橫幅，上面寫著：「我抵制猶太人，是為主而戰！」

這種以上帝的名來作惡的行徑，正是上帝嚴厲禁止以色列民的：「不可妄稱耶和華－你上帝的名；因為妄稱耶和華名的，耶和華必不以他為無罪」（出埃及記20章7節）。這條誡命包含：濫用上帝的名出言詛咒；不小心踢到腳趾或砸到手指時，輕率地呼喊上帝的名；歪曲事實，假借上帝的名義，行邪惡的事。

縱然有人說，我們正在做的事是在為上帝工作，但我們不能因此就斷定自己是在服事上帝。我們必須以禱告的心，按著上帝所啟示的聖經真理，檢視我們所做的一切。我們怎麼知道自己是在服事上帝呢？詩篇119篇9節說：「要遵行祢的話！」這位吩咐我們要「常常竭力多做主工」的上帝（哥林多前書15章58節），已經透過聖經告訴我們什麼是主的工作。讓我們遵行祂的話！

The vintage photograph from World War II, taken outside a town’s Nazi headquarters, carries a warning for all of us. In the photo, a comfortably dressed woman is crossing the street. A man in a suit walks down the sidewalk, while another has stopped to read a bulletin board on the corner of the building. All seem oblivious to the large banner hanging above the headquarters’ front door, half as long as the building. It reads, “By resisting the Jew, I fight for the work of the Lord.”

This kind of treachery is what God had in mind when He commanded, “You shall not misuse the name of the Lord your God, for the Lord will not hold anyone guiltless who misuses his name” (Exodus 20:7). This command covers misusing His name when we curse or when we carelessly shout God’s name when we stub a toe or smash a finger. It also includes perversion—using God’s name as cover for evil.

We shouldn’t assume we’re doing God’s work simply because others say we are. We must prayerfully check our work with what God reveals in the Bible. How can we know we’re serving Him? Psalm 119:9 says, “By living according to your word.” The God who commands us to “always give [ourselves] fully to the work of the Lord” has told us what that work is in His holy book (1 Corinthians 15:58). Let’s listen to Him.
