The Bible does not deny that we were various things—addicts, homosexuals, hateful, prideful, pornographic masturbators—but that is what we were (past tense) (1 Cor. 6:9-11; Titus 3:3-5). The emphasis in Scripture is on what we are and what we are called to be. The Christian does not say, Hello, my name is _____ and I am an X Y or Z.” The Christian says I was dead, but now I am alive. The Christian says I am a struggling sinner, yet I am a saint. The Christians says I am a new creation; I am transformed.
Jesus never expected us simply to turn the other cheek, go the second mile, bless those who persecute us, give unto them that ask, and so forth. These responses, generally and rightly understood to be characteristic of Christlikeness, were put forth by him as illustrative of what might be expected of a new kind of person – one who intelligently and steadfastly seeks, above all else, to live within the rule of God and be possessed by the kind of righteousness that God himself has, as Matthew 6:33 portrays. Instead, Jesus did invite people to follow him into that sort of life from which behavior such as loving one’s enemies will seem like the only sensible and happy thing to do. For a person living that life, the hard thing to do would be to hate the enemy, to turn the supplicant away, or to curse the curser… True Christlikeness, true companionship with Christ, comes at the point where it is hard not to respond as he would.
The church's primary purpose is not to make America more Christian, but to make American Christians less American and Rwandan Christians less Rwandan. We are no longer Rwandans or Americans, neither Hutu nor Tutsi. If we are in Christ, we have become part of a new creation.
The purpose of the local church is not primarily to be one's church home or extended family, though it can be at times. And it is not to survive by obtaining more people for its support base. Its purpose is to invite people to be part of the true mission of the church. Reception into the church is only a threshold to involvement in its mission. The task of the church is not to accumulate attendees. The church is a school for developing agents of the new creation from among those who are the beneficiaries of God's grace.
