In 2 Tim. 2:22 Paul tells us to pursue righteousness. What does that mean? At the most basic level this means that I’m to pursue that which is right. But what or whom is ultimately the source of all things right? God. Therefore by pursuing God and I am pursuing what is right, I am pursuing pure righteousness. Also I must remember that there is no good in me and that all my “righteous” deeds are filthy rags before God (Isa. 64:6). So it would not be right for me to pursue my own righteousness, for it is absent and non-existent in me. But I can pursue an alien righteousness that has been put into me, the glorious and perfect obedience of Jesus Christ (2 Cor. 5:21). Thus, by pursuing Christ I’m pursuing what is right. It is right for to lay aside my old man and put on the new man, which has been created in righteousness (Eph. 4:22-24). I am to labor to present the members of my body to God as instruments and tools of righteousness. Pursuing sanctification in my new man and my members is right. If I present myself as a slave to obeying God, it will end in righteousness (Rom. 6:13-16).
Therefore, because Christ is the fountain of righteousness and contains all righteousness, if I pursue Christ, I pursue what is right, I pursue righteousness. But, I don’t do this for the sake of my own righteousness, or for the sake of being seen as righteous before men, because in reality I am not righteous and I cannot add any right-ness to me. I pursue the righteousness of Christ to pursue what is right, to pursue that which is most worthy of being pursued, namely, Christ!
