Philippians 3:1-6 (KJV)
3 Finally, my brethren, rejoice in the Lord. To write the same things to you, to me indeed is not grievous, but for you it is safe.
2 Beware of dogs, beware of evil workers, beware of the concision.
3 For we are the circumcision, which worship God in the spirit, and rejoice in Christ Jesus, and have no confidence in the flesh.
4 Though I might also have confidence in the flesh. If any other man thinketh that he hath whereof he might trust in the flesh, I more:
5 Circumcised the eighth day, of the stock of Israel, of the tribe of Benjamin, an Hebrew of the Hebrews; as touching the law, a Pharisee;
6 Concerning zeal, persecuting the church; touching the righteousness which is in the law, blameless.
Rejoice in the Lord - Be always happy; but let that happiness be such as you derive from the Lord.
To write the same things - He means those which he had formerly preached to them or to other Churches, for he had but one Gospel; and we may rest assured that the doctrine of this epistle was the same with his preaching.
For you it is safe - It is much better to have these Divine things committed to writing than confided to memory. By the latter they may be either lost or corrupted, by the former they will be preserved.
