I think Brooke's definition = Holly's definition, plus time.
I believe that Brooke writes from the perspective of someone who, like me, grew up in the church, has lived with it their whole life, and feels constantly challenged to keep their faith vibrant and invigorated. For many longtime Christians, no less a definition of faith than Brooke's is necessary, or it wouldn't be authentic faith at all.
But I think it is important to introduce the notion of humility and God-dependence to the definition of what it is to be a Christian. I think of those vineyard workers who got in at the very last hour, and I feel that what all authentic Christians must have in common is a belief that they are not capable of pleasing God on their own merits. All Christians, whether recent converts or lifelong servants, must believe that they are completely dependent on God's provision and not their own works if they are to be in fellowship with God. I believe this is the quality that God has looked for in humanity throughout history, whether Old Testament saint, New Testament apostle, American philanthropist, or animistic tribesman. For each and every one of us, the question is, have we looked at the glory of the God who created us, and the shortcomings within our own hearts and then thrown ourselves on God's mercy and declared like Job, "There must be a mediator who can make peace between God and me, someone outside myself who can bridge the gap between God's righteousness and my own weakness."
This whole discussion demonstrates that a relationship with God is somewhat
like a prism--we're all examining the same gem, but it reflects back different
things depending on our perspective.
That to me is the bare minimum definition of what it means to be a Christian--to believe that Jesus Christ was that mediator and God's provision when we could do nothing redeeming for ourselves. For those who have never heard of Jesus, I believe that the stirrings of such a natural theology are what God responds to, and that He will move heaven and earth to introduce His Son to such a humbled heart.
And once we have become a Christian, the challenge is to keep humility and thankfulness at the forefront of our attention, motivating our actions, and that authenticates the reality of our faith.
This whole discussion demonstrates that a relationship with God is somewhat like a prism--we're all examining the same gem, but it reflects back different things depending on our perspective. That is why the Bible chronicles God's workings in the lives of hundreds of vastly different people--because it is possible to have vastly different experiences of the same God.
Liberal theologians use that as a stumbling block, and try to say that God is whatever you want him to be; I think what we are saying is that God is one clear thing--immutable--revealed perfectly in Jesus Christ--but once Jesus takes up residence in a human heart, He expresses himself in a thousand surprising and beautiful ways.
Holly says: The best part of this discussion is we're thinking and talking about what it means to be a Christian. The more often I discuss this topic with other Christians, the more comfortable I become talking about it with friends who aren't Christians.
Thinking about it also gives me a greater confidence in what I believe, and what's important to my faith. It's easy to get caught up in the worldview of Christians: as crazed, hypocritical Bible thumpers, religious snobs who wear gold crosses around their necks and thumb their noses at the rest of the "lost sinners" of the world. Whenever I see someone with a "Jesus Loves You" bumper sticker who drives like a maniac and flips other drivers the bird, I think, "Boy, I gotta prove Christians aren't like that. I gotta counter those stereotypes." And I put my energy into trying to compensate, telling others, "Not all Christians are like that."
Rather, my focus should be on Jesus: who he is, how he's made a difference in my life, why I'm so affected by the things he said and did. When others hear about Jesus and see his effect on me, it will move them so much more than me constantly repeating, "Not all Christians are like that. Not all Christians are like that. Not all ... " (I know, you get the point.)
To close, here's a verse that popped into my head when I read Kevin's comment:
Now all we can see of God is like a cloudy picture in a mirror. Later we will see him face to face. We don't know everything, but then we will, just as God completely understands us.
--1 Corinthians 13:12, CEV
