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.
Many things have changed since Old Testament times. For instance, the Lord visited His people in the temple or tabernacle in the Old Testament by dwelling between the cherubims on the ark of God (Psalm 80:1). This ended especially with the onset of the New Testament and the permanent indwelling of God's Spirit within believers. The Lord stressed, “. . . that ye are the temple of God, and that the Spirit of God dwelleth in you” (1 Corinthians 3:16). For this reason, the New Testament does not place as much emphasis on reverence in the physical house of God. Regardless, the Lord is not silent concerning our behaviour in His house. We should behave ourselves both respectfully and properly (1 Timothy 3:15). Of all people, Bible believers should demonstrate reverence in the house of God so that others get a sense for our awe of God and His goodness.
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.
