A basic definition of communication involves making things common. When we speak to others, we express what is in our minds and hearts making those thoughts common with others. The Bible warns the believer in Ephesians 4:29 to “Let no corrupt communication proceed out of your mouth, but that which is good to the use of edifying, that it may minister grace unto the hearers.” The words that come out of our mouths should edify or build up others, not demean and degrade them. They should be strengthened by what we say. Keep in mind that corrupt communications weaken the believer (1 Corinthians 15:33). This is why Christians are instructed to put off all “filthy communication” (Colossians 3:8).
Christians in every age have faced varied battles ranging from small skirmishes to life-ending combat. God’s word tells the believer to equip himself as a good soldier of Jesus Christ (2 Timothy 2:3) by putting on “the whole armour of God.” This armour enables those engulfed in the battle to “stand against the wiles of the devil.” The apostle Paul identifies this armour and the importance of every element. Interestingly, as he refers to “the shield of faith,” he suggests taking it “above all.” Faith, though often overlooked, remains a crucial element within the saint’s spiritual arsenal. The Bible drives home this truth by pointing out that the shield of faith can “quench all the fiery darts of the wicked.” Without faith, the believer stands exposed and vulnerable. It is utterly impossible to “be strong in the Lord” apart from a steadfast faith in God and His word. While the sword (the Bible) works on the offense, faith protects and shields.
