Righteousness

Many say today that all are unrighteous, but these passages shout to someone the glorious news that righteousness comes with salvation. Salvation is not earned by the righteousness we obtain; but righteousness is received by those who believe.

Righteousness is something to seek after:
But seek ye first the kingdom of God, and his righteousness; and all these things shall be added unto you. (Matt 6:33)
Righteousness makes up the kingdom:
For the kingdom of God is not meat and drink; but righteousness, and peace, and joy in the Holy Ghost. (Rom 14:17)
By Jesus we are filled with righteousness:
Being filled with the fruits of righteousness, which are by Jesus Christ, unto the glory and praise of God. (Phil 1:11)
By faith we receive it:
But what things were gain to me, those I counted loss for Christ. Yea doubtless, and I count all things but loss for the excellency of the knowledge of Christ Jesus my Lord: for whom I have suffered the loss of all things, and do count them but dung, that I may win Christ, And be found in him, not having mine own righteousness, which is of the law, but that which is through the faith of Christ, the righteousness which is of God by faith: (Phil 3:7-9)
We have been changed from sin to righteousness:
For I am not ashamed of the gospel of Christ: for it is the power of God unto salvation to every one that believeth; to the Jew first, and also to the Greek. For therein is the righteousness of God revealed from faith to faith: as it is written, The just shall live by faith.
Who his own self bare our sins in his own body on the tree, that we, being dead to sins, should live unto righteousness: by whose stripes ye were healed (1 Pet 2:24)
