1 Corinthians 16:13

Watch ye, stand fast in the faith, quit you like men, be strong.

'Watch ye' -'Keep your eyes open for spiritual danger' (Tay) 'The five tenses are present to express durative and continuous action..means..be not careless, indifferent, or easily deceived!' (Lenski pp. 772,773) Watchful in regard to the enemy (1 Peter 5:8) and corrupting influences (Acts 20:31). 'Stay awake' (Robertson p. 202)

'stand fast in the faith' -'stand firm in your faith' (Gspd). Stop wavering between belief and unbelief, sound doctrine and false doctrine, righteousness and immorality. Stand for Christ and don't move! Faith here is probably 'the faith', the contents of Christian teaching. (1 Corinthians 15:1) 'Its opposite is to depart from or to fall way from the faith, 1 Timothy 4:1. (Lenski p. 773)

'quit you like men' -'act like men' (NASV) 'Be men constantly..Show yourselves men always' (Lenski p. 774) When confronting sin and error, we cannot be fearful or timid.

'be strong' -'show strength' (Lenski p. 774) And the Corinthians had been demonstrating "weakness" and not strength. Don't demonstrate fickleness, heedlessness, impatience, immaturity, childishness..DEMONSTRATE STRENGTH! (See Ephesians 6:10)

'He calls them to vigilance. Be watching! He calls them to doctrinal steadfastness. Be standing! Be standing in the faith! He calls them to the courage of manhood and the response of manhood. Be playing the man! (How babyish they had been)..In all of this there is the picture of. warrior, bent on battle. Someone who will not give an inch to the Devil. Someone who will guard and stand in the faith without retreating an inch...But such people can become as unapproachable and as unyielding as. mount Sinai and will blast the transgressor with. blot of righteous indignation at the slightest provocation. So Paul adds: "Be letting everything that you do be done in love!"' (McGuiggan p. 217)
