The Core of a Christian

Scripture Reference: Philippians 3:1-7
1 Finally, my brethren, rejoice in the Lord. For me to write the same things to you is not tedious, but for you it is safe.  2 Beware of dogs, beware of evil workers, beware of the mutilation! 3 For we are the circumcision, who worship God in the Spirit, rejoice in Christ Jesus, and have no confidence in the flesh, 4 though I also might have confidence in the flesh. If anyone else thinks he may have confidence in the flesh, I more so: 5 circumcised the eighth day, of the stock of Israel, of the tribe of Benjamin, a Hebrew of the Hebrews; concerning the law, a Pharisee; 6 concerning zeal, persecuting the church; concerning the righteousness which is in the law, blameless.  7 But what things were gain to me, these I have counted loss for Christ.
