I contend that anyone who is "offended" by the statements of others are by default in a position of weakness from the very start! Those who are easily offended are most often clinging to some worldly (ungodly) belief system or philosophy which is not in alignment with the "truth" of Scripture (Holy Bible). I've seen numerous slurs made against the Bible as being an illegitimate book written by madmen. I've seen people both in the workplace, in (so-called) "Jewish" Hollywood, and other places where people say "Jesus fn Christ" in every other sentence or paragraph. The examples of antichristianity are everywhere in just about every form one can ever imagine in a Judaic-run (Christ-rejecting) world run by the "Synagogue of Satan" referenced in Revelation 2:9, 3:9.
But, am I offended? The answer is "no." The reason is, there is One God, Son, and Holy Spirit. This all-powerful Trinity does NOT need me! I need Them! The Trinity needs no defense... certainly NOT any I could ever provide. My job in this life on earth is simply to spread the "truth"... God's truth. Nothing more, nothing less! Those who criticize the Biblical points that I make do so to their own peril. Those who choose their own way to live in violation of the ways of God are setting themselves up to face God's judgments both in this life and beyond.
When I hear people cursing or saying "Jesus fn Christ," I am not offended! Rather, I pity those souls who will eventually see God's holy hatred and wrath in action!
