Philippians 3:15
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. 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.
Those called perfect are those mature in the Christian life. The words were declared in vision to Paul, to whom God gave many revelations, as truth revealed to him, and they express the fundamental principles of the law that declares the whole duty of man. Christian perfection is the highest perfection of character to be aimed at throughout a lifetime, which involves acknowledging that perfection has not yet been attained and not counting oneself as having already attained it.
To be thus minded means to count former gain as loss for Christ, to count all things as loss for the excellency of knowing Christ Jesus, to suffer the loss of all things to win Christ and be found in Him with righteousness through faith in Christ and not with own righteousness of the law, and to know Him and the power of His resurrection and the fellowship of His sufferings in conformity to His death. It also means to share Paul's forward-looking purpose and way of thinking by forgetting what is behind, reaching forward to what is before, and pressing toward the mark for the prize of the high calling of God in Christ Jesus, continually reaching out for higher and still higher attainments. This mindset involves confessing every sin, remaining constantly on guard, and never standing still or turning back but ever pressing on.
If in anything believers are otherwise minded and differ in understanding, God shall reveal even this unto them and show them their mistakes by the counsel of His grace, so that no one seeking truth will be left to grope along in doubt and perplexity. When God shows believers their mistakes, they must receive the correction in the meekness of holiness, letting pride and self-importance die. The verse's following counsel is to keep living by the same rule and the spiritual ground already reached and to mind the same thing and remain united in purpose, which calls believers and workers to avoid divisions in the church.
This unity includes following together Paul and marking those who walk as his example, while giving no encouragement to the many who walk as enemies of the cross of Christ, whose end is destruction and who mind earthly things. The teaching is recorded for the benefit of all who desire to be sincere, earnest, whole-hearted Christians obedient to all God's requirements, and the lessons of Philippians 3 should be carefully studied, practiced, and heeded so Christians grow in Christ and in understanding of truth.
