Acts 7:51

You people are unbending and unrepentant in your hearts and [unwilling to listen with] your ears. You are always resisting [the desires of] the Holy Spirit just like your forefathers did.

Philippians 3:3

For we [Christians] are the [true] circumcision [i.e., the real "Jews" in God's eyes. See Rom. 2:28-29]. We worship by means of God's Holy Spirit [i.e., are empowered and motivated by the Holy Spirit], and boast in [the person and work of] Christ Jesus, and [we] place no confidence in the flesh [i.e., in any outward ritual or status for salvation].

Colossians 2:11

In [fellowship with] Him you people were also circumcised with a circumcision not performed by human beings, but performed by Christ, consisting of the removal of the body of [sinful] flesh.

Matthew 23:12

And whoever exalts himself [as important] will be humbled, and whoever humbles himself will be exalted [as important].

Luke 14:11

For every person who exalts himself [as important] will be humbled, but the person who humbles himself will be exalted [as important]."

Luke 18:14

I tell you, this man went back home right with God instead of the other man. For every person who exalts himself [as important] will be humbled, but whoever humbles himself will be exalted [as important]."

Romans 2:28-29

For that person is not a Jew who is one [merely] on the outside. And circumcision is not [merely] an outward physical ordinance.

Galatians 5:6

For in [our relationship with] Christ neither the practice of circumcision nor refraining from its practice matters in any way; but [all that really matters is having a genuine] faith [in Christ] that causes us to work [for Him] out of a genuine love [for Him and others].

James 4:6-9

But He gives [us] more unearned favor [i.e., to overcome the world]. Therefore, the Scripture says [Prov. 3:34], "God opposes proud people, but gives unearned favor to those who are humble."

1 Peter 5:5-6

And in the same way, you younger [Christians] should be [respectfully] submissive to the older ones. And all of you should [be willing to] humbly serve one another, for God stands opposed to [the efforts of] proud people, but extends His unearned favor to those [who serve] with humility.
