“Out of the abundance of the heart the mouth speaketh” (Matthew 12:34). As such, the words that proceed from our mouths provide helpful insights into the condition of our hearts. A man can only deceive with his words for so long; eventually, his speech exposes the reality of his heart's condition. The Bible reinforces this truth when it says, “the words of the pure are pleasant words” (Proverbs 15:26). The Bible also identifies words of praise to God as “pleasant” words (Psalm 135:3; Psalm 147:1). Impure words manifest an unpleasantness. Whereas, a pure heart utters pure words and speaks of the Lord and of His goodness.
Doing the right thing is always the right thing to do and yields great benefits. For instance, consider what the Bible has to say about diligence. God’s word promises that diligence brings an increase of substance (Proverbs 10:4; Proverbs 13:4; Proverbs 21:5) and promotion (Proverbs 12:24; Proverbs 22:29). In other words, as the saying goes, hard work pays off. It is not difficult to prove that these benefits manifest themselves in the lives of God’s people who are diligent. Joseph and Daniel are two great examples of those who were diligent and their diligence brought them obvious promotion. Abraham and Job are great examples of diligent men who experienced a great increase of substance. A word of caution might be appropriate here. Men are not to be diligent merely for the sake of reaping its inherent benefits, but should be diligent for the sake of the One who called them to be diligent.
