Sometimes the most difficult and significant tasks involve the simplest truths. For instance, every Christian should quickly learn that vengeance belongs unto the Lord. God confirms as much throughout scripture (Deuteronomy 32:35; Psalm 94:1; Romans 12:19; Hebrews 10:30). This should be understandable as only the Lord has all the necessary information to execute just vengeance 100 percent of the time. When man attempts to execute vengeance, he often does so out of an improper motive or without key information of the evil that appears to have been done. Furthermore, when a believer takes vengeance into his own hands, he robs the Lord of His right and responsibility to exact vengeance at the right time and in the right manner.
Our words should never be used by the Devil as weapons to destroy or discourage others. Any problem with our words reveals a problem with our heart: “out of the abundance of the heart the mouth speaketh” (Matthew 12:34). The mouth can exhibit good or bad and our actions reveal the heart of the problem when the Bible says, “out of the heart proceed evil thoughts, murders, adulteries, fornications, thefts, false witness, blasphemies” (Matthew 15:19). This is why our words are not always profitable to those who hear them. Yet, God admonishes us to “let no corrupt communication proceed out of” our mouth. Believers are instead encouraged to make sure their words are “good to the use of edifying.” The saint of God should speak words that God can use to build up other saints in the faith.
