Let us therefore, as many as be perfect, be thus minded: and if in any thing ye be otherwise minded, God shall reveal even this unto you. As many as be perfect - As many as are thoroughly instructed in Divine things, who have cast off all dependence on the law and on every other system for salvation, and who discern God calling them from above by Christ Jesus; be thus minded; be intensely in earnest for eternal life, nor ever halt till the race is finished.
The word τελειοι, perfect, is taken here in the same sense in which it is taken 1 Corinthians 14:20 : - Be not Children in understanding - but in understanding be ye Men, τελειοι γινεσθε, be ye perfect - thoroughly instructed, deeply experienced. 1 Corinthians 2:6 : - We speak wisdom among the perfect, εν τοις τελειοις, among those who are fully instructed, adults in Christian knowledge. Ephesians 4:13 : - Till we all come - unto a perfect man, εις ανδρα τελειον, to the state of adults in Christianity. Hebrews 5:14 : - But strong meat belongeth to them that are of full age, τελειων, the perfect - those who are thoroughly instructed and experienced in Divine things. Let us therefore, says the apostle, as many as be perfect - as have entered fully into the spirit and design of the Gospel, be thus minded, viz. Forget the things which are behind, and stretch forward along the mark for the prize.
If in any thing ye be otherwise minded - If ye have not yet entered into the full spirit and design of this Gospel, if any of you have yet remaining any doubts relative to Jewish ordinances, or their expediency in Christianity, God shall reveal even this unto you; for while you are sincere and upright, God will take care that ye shall have full instruction in these Divine things.
