5 Surely I have taught you statutes and judgments, just as the Lord my God commanded me, that you should act according to them in the land which you go to possess. 6 Therefore be careful to observe them; for this is your wisdom and your understanding in the sight of the peoples who will hear all these statutes, and say, ‘Surely this great nation is a wise and understanding people.’ (Deuteronomy 4:5–6, NKJV)
Through Moses, the Lord repeatedly exhorted Israel “to be careful to observe” His commandments (Deut. 5:1, 32; 6:3). Was careful obedience only reserved for Israel because God commanded them from Mt. Sinai (Deut. 4:13-14)? No, the Lord God has always expected people to obey His commands, promising blessings to the obedience and warning the disobedient of punishment (Gen. 2:16-17; Exod. 20:5-6). God’s desire and expectation that we obey Him remains true under the new covenant, the gospel of Christ. For instance, Jesus expects those who call Him “Lord, Lord” to do what He says (Luke 6:46). We must do the will of the Father to enter the kingdom of heaven (Matt. 7:21). Christ is the “author of eternal salvation to all who obey Him” (Heb. 5:9). But “to those who are self-seeking and do not obey the truth but obey unrighteousness—indignation and wrath, tribulation and anguish” (Rom. 2:8-9). No wonder Paul commended Timothy for carefully following “good doctrine” from the apostle (1 Tim. 4:6; 2 Tim. 3:10). God blesses obedience and punishes disobedience. This truth abides forever.
