Philippians 3
1. Finally, my brothers, rejoice in the Lord! It is no trouble for me to write the same things to you again, and it is a safeguard for you.
2. Watch out for those dogs, those men who do evil, those mutilators of the flesh.
3. For it is we who are the circumcision, we who worship by the Spirit of God, who glory in Christ Jesus, and who put no confidence in the flesh--
4. though I myself have reasons for such confidence. If anyone else thinks he has reasons to put confidence in the flesh, I have more:
5. circumcised on the eighth day, of the people of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; in regard to the law, a Pharisee;
6. as for zeal, persecuting the church; as for legalistic righteousness, faultless.
"For the mind set on the flesh is death, but the mind set on the Spirit is life and peace, because the mind set on the flesh is hostile toward God; for it does not subject itself to the law of God, for it is not even able to do so.". Romans 8:6-7
"But a natural man does not accept the things of the Spirit of God, for they are foolishness to him; and he cannot understand them, because they are spiritually appraised." 1 Corinthians 2:14
For the wrath of God is revealed from heaven against all ungodliness and unrighteousness of men who suppress the truth in unrighteousness, because that which is known about God is evident within them; for God made it evident to them.
For since the creation of the world His invisible attributes, His eternal power and divine nature, have been clearly seen, being understood through what has been made, so that they are without excuse.
For even though they knew God, they did not honor Him as God or give thanks, but they became futile in their speculations, and their foolish heart was darkened.
Professing to be wise, they became fools, and exchanged the glory of the incorruptible God for an image in the form of corruptible man and of birds and four-footed animals and crawling creatures.
Therefore God gave them over in the lusts of their hearts to impurity, so that their bodies would be dishonored among them.
For they exchanged the truth of God for a lie, and worshiped and served the creature rather than the Creator, who is blessed forever. Amen.
Romans 1:18-25
in that they show the work of the Law written in their hearts, their conscience bearing witness and their thoughts alternately accusing or else defending them
Romans 2:15
