“The ends justify the means” is a worldly philosophy with no place in the life of a believer. Proverbs sheds wisdom on the philosophy of “the ends justify the means.” Gain gathered through ungodly means will ultimately not profit us (Proverbs 10:2; 20:17). Because God alone “weighs” our heart and spirit (Proverbs 16:2; 21:2-3), we should seek to always do what is right and have uncompromising, biblical character. The New Testament also instructs us to act according to our new nature (1 Peter 1:15–16; Ephesians 5:8-11) rather than forsake godliness to achieve certain results. We should seek to always do what is honorable in God’s sight (and others) (2 Corinthians 8:21) and do everything for the glory of God (1 Corinthians 10:31-32) instead of ourselves—even if it means doing what is less convenient for us. The Bible also calls us to do all things from “pure heart and a good conscience and a sincere faith” (1 Timothy 1:5). There will be many opportunities in life to take the easier road that involves sinful compromises, but God is with us during such times and He will provide for us a way to escape temptation (1 Corinthians 10:13). God calls us to live with integrity and holiness in every action, trusting Him to accomplish good outcomes rather than compromising our character because true success comes from obedience and faithfulness, not shortcuts or moral compromise.
Often, when a person says "the ends justify the means" they are saying that if the end result is noble enough, it will justify whatever measures are taken to achieve it. For example, if your goal is to save lives, it's okay to cheat, steal, and lie to accomplish your goal. More often, the scenario is something less drastic, such as lying to someone to spare their feelings, or running up a credit card because the goal is to buy Christmas gifts. It is quite likely, if we each were to examine our lives, we would see ourselves justifying the ends with the means in many areas. The law of God, as seen in the Bible, is clear about what is moral and immoral. The reason "the ends justify the means" is such an ethical dilemma is because it allows small immoralities to take place in order to achieve larger moralities. The problem with this philosophy is that it puts the law into the hands of human beings—which, in turn, makes the “law” subjective to each person’s opinion. The ultimate reason for justifying sin is fear. We are afraid we won’t have enough money, so we lie, steal, and cheat or we are afraid we will live meaningless lives, so we puff ourselves up with pride. The answer to such dysfunction is to trust God (Proverbs 3:5–6). As God’s child, we can rest assured that He cares for us and will provide what we need. We do not need to make “the ends justify the means,” rather, we should put our full faith and trust in the God who will take care of His children in His own timing and His own ways (Matthew 6:25-34).
