Philippians 3:2-21 New Revised Standard Version (NRSV)
2 Beware of the dogs, beware of the evil workers, beware of those who mutilate the flesh! 3 For it is we who are the circumcision, who worship in the Spirit of Godand boast in Christ Jesus and have no confidence in the flesh— 4 even though I, too, have reason for confidence in the flesh.
If anyone else has reason to be confident in the flesh, I have more: 5 circumcised on the eighth day, a member of the people of Israel, of the tribe of Benjamin, a Hebrew born of Hebrews; as to the law, a Pharisee; 6 as to zeal, a persecutor of the church; as to righteousness under the law, blameless.
7 Yet whatever gains I had, these I have come to regard as loss because of Christ. 8 More than that, I regard everything as loss because of the surpassing value of knowing Christ Jesus my Lord. For his sake I have suffered the loss of all things, and I regard them as rubbish, in order that I may gain Christ 9 and be found in him, not having a righteousness of my own that comes from the law, but one that comes through faith in Christ, the righteousness from God based on faith. 10 I want to know Christ and the power of his resurrection and the sharing of his sufferings by becoming like him in his death, 11 if somehow I may attain the resurrection from the dead.
12 Not that I have already obtained this or have already reached the goal; but I press on to make it my own, because Christ Jesus has made me his own. 13 Beloved, I do not consider that I have made it my own; but this one thing I do: forgetting what lies behind and straining forward to what lies ahead, 14 I press on toward the goal for the prize of the heavenly call of God in Christ Jesus. 15 Let those of us then who are mature be of the same mind; and if you think differently about anything, this too God will reveal to you. 16 Only let us hold fast to what we have attained.
17 Brothers and sisters, join in imitating me, and observe those who live according to the example you have in us. 18 For many live as enemies of the cross of Christ; I have often told you of them, and now I tell you even with tears. 19 Their end is destruction; their god is the belly; and their glory is in their shame; their minds are set on earthly things. 20 But our citizenship is in heaven, and it is from there that we are expecting a Savior, the Lord Jesus Christ. 21 He will transform the body of our humiliation that it may be conformed to the body of his glory, by the power that also enables him to make all things subject to himself.
Philippians 4:4-7 New Revised Standard Version (NRSV)
4 Rejoice in the Lord always; again I will say, Rejoice. 5 Let your gentleness be known to everyone. The Lord is near. 6 Do not worry about anything, but in everything by prayer and supplication with thanksgiving let your requests be made known to God. 7 And the peace of God, which surpasses all understanding, will guard your hearts and your minds in Christ Jesus.
