To be like Jesus, in Scripture is to be like Paul, to some extent. And to follow Paul as he followed Christ involves not having a righteousness of our own, but Christ's righteousness, or the righteousness from God which comes through faith in Christ.
Paul states in the Philippians 3 passage that his desire was to be found in Christ. This seems to be something that Paul was not taking for granted.
In our evangelical world it seems to me that we do take this for granted. Once someone "accepts Christ" they are "in Christ" and this is no longer a concern. Unless I'm reading this passage wrongly, for Paul it was a passion. Paul knew what it was like to be righteous in his own efforts in keeping God's law. He followed the prescribed keeping of the law, faultlessly. There surely was a sense of failure though in seeking to keep the law. I think I see echoes of this in Romans 7, which I think looks at life in seeking to keep God's law apart from Christ and without the help of the Spirit. I believe the "I" there is a personification common in that time in writing, for humankind's efforts to keep God's law written outwardly and inwardly.
Oftentimes I have wondered about myself. I have been a Christian now for many years (nearly 35!), but so much of the time I have been more taken up with my own efforts to live the Christian life. Of course in that is failure, although "in Christ" God is always at work in us.
But like Paul, I want to no longer take this for granted. I want to be found in Christ and I want to know Christ better. I want my life to be answerable to Jesus Christ. Of course there is much involved in that, not least of which is our union in the Body of Christ with others who are in Jesus.
What about you? Do you see this as a concern in your life as a Christian? Do we take this for granted when maybe we should not? Why or why not?
