Finally, my brothers, rejoice in the Lord. To write the same things to you is no trouble to me and is safe for you.
Look out for the dogs, look out for the evildoers, look out for those who mutilate the flesh. For we are the circumcision, who worship by the Spirit of God and glory in Christ Jesus and put no confidence in the flesh—though I myself have reason for confidence in the flesh also. If anyone else thinks he has reason for confidence in the flesh, I have more: circumcised on the eighth day, of the people of Israel, of the tribe of Benjamin, a Hebrew of Hebrews; as to the law, a Pharisee; as to zeal, a persecutor of the church; as to righteousness under the law, blameless. But whatever gain I had, I counted as loss for the sake of Christ. Indeed, I count everything as loss because of the surpassing worth of knowing Christ Jesus my Lord. For his sake I have suffered the loss of all things and count them as rubbish, in order that I may gain Christ and be found in him, not having a righteousness of my own that comes from the law, but that which comes through faith in Christ, the righteousness from God that depends on faith—that I may know him and the power of his resurrection, and may share his sufferings, becoming like him in his death, that by any means possible I may attain the resurrection from the dead.
Not that I have already obtained this or am already perfect, but I press on to make it my own, because Christ Jesus has made me his own. Brothers, I do not consider that I have made it my own. But one thing I do: forgetting what lies behind and straining forward to what lies ahead, I press on toward the goal for the prize of the upward call of God in Christ Jesus.
(Philippians 3:1-14 ESV)
O LORD, who shall sojourn in your tent?
Who shall dwell on your holy hill?
He who walks blamelessly and does what is right
and speaks truth in his heart;
who does not slander with his tongue
and does no evil to his neighbor,
nor takes up a reproach against his friend;
in whose eyes a vile person is despised,
but who honors those who fear the LORD;
who swears to his own hurt and does not change;
who does not put out his money at interest
and does not take a bribe against the innocent.
He who does these things shall never be moved.
(Psalm 15 ESV)
