1Peter 1:13-14 Wherefore gird up the loins of your mind, be sober, and hope to the end for the grace that is to be brought unto you at the revelation of Jesus Christ; As obedient children, not fashioning yourselves according to the former lusts in your ignorance:
‘Gird up the loins of your mind, be sober …’ Seven commands are given here for Christians: Gird up the loins of your mind (1:13). This means to brace up and take courage in face of the trials that one is called to go through. Be sober (1:13). The Greek word nepho, to live soberly [not under the influence of any alcohol or pharmaceutical products] and righteously (cp. Tit. 2:11-12). Hope to the end for the grace and salvation that are to be brought at the coming of Christ (1:13; Rom. 8:24-25). This further confirms the fact that all of grace and salvation is not received at the remission of sins. Do not pattern after your former life of sin (1:14; Eph. 2:1-3). You are new creatures and you must live new lives (2Cor. 5:17-18). Be holy in all your manner of life (1:15). You are to pattern after God in all things (1:16; 2:21-23). Pass the time of your sojourning here in fear (1:17; 1Cor. 10:12-13), that is to have a holy reverence towards God and His commandments that are there for our protection. See that you love one another with a pure heart fervently (1:22; John 13:34-35; 15:12-13).
‘And hope to the end for the grace that is to be brought unto you at the revelation of Jesus Christ’ this is the 3rd New Testament prophecy in 1Peter that is unfulfilled. It will be fulfilled at the second coming of Christ, at which time the full blessings of grace and of eternal redemption will begin to be realized by all men on earth.
‘As obedient children’ this expression is the same as ‘children of obedience’ which stands in direct opposition of ‘children of disobedience.’ We are a child of whatever we choose to follow, and it can never be contrasts. You are either a child of obedience, light (Luke 16:8; John 12:36), righteousness and thus a child of God (Matt. 5:9, 45; Luke 20:36; Rom. 8:16; Gal. 3:26), or you are a child of disobedience (Eph. 2:2; 5:6), darkness (1Thess. 5:5), unrighteousness and thus a child of satan (Matt. 13:38; Acts 13:10; 1John 3:10).
‘Fashioning’ the Greek word suschematizo meaning to conform to another’s example.
‘According to the former lusts in your ignorance’ a nine-fold former state is described in Ephesians 4:17-19 of a sinner’s life: To be vain in mind (Eph. 4:17; cp. Eph. 2:11); and dark in understanding (Eph. 2:12; 4:18); alien to God’s life; ignorant of God; blind in heart (2Cor. 4:4); past feeling; lustful (Eph. 4:19; Gal. 5:19); unclean; greedy (Eph. 5:3; 2Cor. 6:10).
