Only a foolish man thinks he can hide anything from the Lord. This includes his thought life. The Lord knows all man’s thoughts (1 Chronicles 28:9) which includes the good (Malachi 3:16) and the bad (Psalm 94:11). David expressed this truth to the Lord when he said, “Thou knowest . . . my thought afar off. . . . For there is not a word in my tongue, but, lo, O LORD, thou knowest it altogether” (Psalm 139:2-4). The Lord Jesus Christ often exhibited this capability during His earthly ministry (Matthew 12:25; Luke 5:22; Luke 6:8; Luke 9:47; Luke 11:17). Even the written word of God reveals this ability by being “a discerner of the thoughts and intents of the heart” (Hebrews 4:12).
A man’s conversation should consistently exhibit a high level of individual contentment. Defining conversation and covetousness will help to better understand Hebrews 13:5. A man’s conversation in the Bible sometimes refers to more than the words he speaks. It frequently refers to his entire way of life. One who lives covetously desires things not belonging to him. The Bible stresses the seriousness of covetousness by connecting it to the sin of idolatry. Combining these two simple truths shows that man should never live his life chasing after things not belonging to him. Why is it so important for a Christian to live a life of contentment? Since God promises to never leave or forsake His own, a discontented Christian lacks a trust in His Creator. Understanding these simple truths should bring great contentment to the believer.
The words content and contentment infer that one is satisfied with life's present conditions (Genesis 37:27; Exodus 2:21). Living contently is the opposite of wanting (Philippians 4:11) and covetousness (Hebrews 13:5) and is strongly associated with godliness (1 Timothy 6:6). Interestingly, contentment is a learned behaviour that believers must put into practice on a consistent basis throughout life. No one is born into the world content. Yet, once learned and practiced consistently, Christians will experience contentment in spite of any circumstance faced. Unfortunately, far too often, Christians exhibit no more contentment than non-Christians. In fact, believers seem to desire and covet the things of the world more and more with each passing year. This covetousness combined with a lack of contentment amongst Christians results in less godliness and a closer association with worldly pleasures.
