Carelessness is a failure of proper judgment: the careless person either does not think at all or does not think things through to their end. It flows from undervaluing something, since the value placed on a person or thing determines the attention paid to it. Proverbs 19:16 says, "He who keeps the commandment keeps his soul, but he who is careless of his ways will die." The Hebrew behind "careless" means to despise or hold in contempt, so the careless man treats his own way of life as meaningless. He wanders wherever lust or emotion leads and ends in destruction, while the commandment-keeper walks steadily toward his goal. God therefore commands carefulness, repeating "be careful to observe" fifteen times in Deuteronomy. Following His way takes focus, effort, attention to detail, and perseverance. A person can be careful in some areas and careless in others, as the Pharisees were: meticulous about their traditions, yet careless about justice, mercy, faith, and the truth. A second Hebrew word, batah, describes complacency, a false sense of security never tested against reality. Isaiah 32 and Amos 6 warn those at ease in Zion, who put off the day of doom, lie down, distract themselves, indulge themselves, and feel no grief over the nation's ruin. This is the Laodicean attitude of needing nothing. Jerusalem fell because she did not consider her destiny (Lamentations 1:9). Proverbs 14:15-16 contrasts the prudent, who consider their steps, with the self-confident fool. The remedy is to think through the consequences of every decision and to seek to please God in all things.

Carelessness toward salvation begins with distraction, which draws the mind from what claims its attention and is the primary motivator of neglect. Nobody is immune, and even a minor distraction can bring a momentary break in thought, confusion, wasted time, and a small measure of carelessness about what one was doing. Left untreated, it grows. Demas, who served alongside Paul for years, is the example: a distraction from the world, likely beginning with a quick thought, was fed by further distractions until he loved this present world and abandoned Paul, the church, and apparently his salvation (II Timothy 4:9-10). Hebrews 2:1-4 warns that we must give earnest heed lest we drift away, as though carried unnoticed by a current, and asks how we can escape if we neglect so great a salvation. Neglect means to fail to heed, to disregard, to ignore, to give little or no attention or care. Accepting the truth is only a beginning and is not enough to complete the course. Neglect also carries guilt, as with the law requiring a fence around a flat Israelite roof: an owner who disregarded it was already guilty. So the answer is to settle now on a fixed focus and an organized plan, and to treat distractions quickly, working through the chaos of the world rather than being drawn away from God's calling.

Everything matters in life, though not to the same degree. The air we breathe matters. What we eat matters. What we drink matters. The clothing we choose to wear matters. What we do with our hair matters. How we drive our cars matters. What we choose to listen to in the way of music matters. What we choose to read matters. How long we choose to sleep matters. What we choose in the way of entertainment matters. The attitudes we allow ourselves to operate in matter. The people we choose to associate with matter. Carelessness in these choices can lead to a life of vanity, filled with meaningless activities that have nothing to do with God's creative purpose or His way of life. Such carelessness may not only be empty but sometimes downright destructive.
