The Bible clearly emphasizes that the Christian warfare is a “fight of faith” (1 Timothy 6:12) against spiritual foes (Ephesians 6:12). With this in mind, it only makes sense that the weapons used in this warfare would also be spiritual in nature. The Christian’s fight needs no physical arms, swords, or weaponry of any kind, yet the weapons of this warfare are “mighty through God to the pulling down of strong holds.” Those religions (and cults) who use physical weaponry to convert others to their “faiths” have never done this at the Lord’s bidding or direction. The Christian faith never has nor ever will convert one single person through use of a physical sword or threat. Instead, God’s people are completely reliant upon the words of God and the God of those words.
From the Old Testament to the New Testament, many things change; however, some themes remain constant. One such theme involves the Lord's desire to use pure things and pure people. God commanded His people in the Old Testament to make sure the things used in the tabernacle were purified (Leviticus 8:15). He also commanded that His servants be purified (Ezra 6:20). In the New Testament, the apostle Paul confirmed the continuation of this theme by saying that “pureness” approved him as a minister of God (2 Corinthians 6:4-6). God still requires those who serve to strive to live pure and holy lives. Impurities hinder the Lord’s effectiveness in our lives though we may not be aware of the hindrance.
