I recently heard somebody refer to faith as a verb. While many verbs are involved in faith, I would say that faith is itself not a verb, but it is a noun.
Faith in Jesus Christ is not believing in Christ. Having faith in Christ is having a relationship with Him. A relationship is a noun. What then does this thing involve? That is a more complex issue.
What does any relationship require? We could probably come up with a long list, but I will note a few that stand out to me.
Trust. We must be able to trust that the people we have relationships will be there for us. Our relationships with colleagues and co-workers is rooted in a trust that we will see them at certain times and places. They will follow through with their duties and responsibilities. Often times my favorite colleagues are not the ones that I work with directly on specific tasks or committees, but the ones that are there to chat about a rough day, a rough class, pop culture, or maybe Foucault.
Our relationships with family are deeper, more intimate, and they usually are longer in duration. The longevity of family relationships often has to do with the fact that such relationships are not as contingent upon geography and situation as relationships with neighbors and co-workers. My relationship with my wife involves both the good times and the bad times. Landing the new job…and getting dismissed are things that I experience with her in ways that I do with nobody else. Part of what makes our relationship such a large part of my life is that what happens to one of us…happens to both of us.
