Do you think it is important to God that we believe we understand the Holy Trinity or do you think He wants us to constantly be trying to understand?
I think that it is important that we have faith that seeks understanding of the Trinity and many other theological concepts - atonement, salvation, forgiveness. Some of these we experience, some of these we seek to understand, and for many of them we do both. In regard to the Trinity, I believe that it is more important to seek a relationship and experience interaction than to think about or try to understand.
I do not think that it is a faithful response to say that we fully understand the Trinity. I think that there is a balance between knowing / understanding and fully understand the Trinity. Our journey at Resurrection is one of knowing, loving and serving God and this is a journey that will likely not be complete in this life.
This question came out of a young adult small group taster last Sunday morning in which I taught about the question "What is the Trinity?"
