In the past few years, a phrase is being used in church community, that is: "down to earth", emphasizing that Christians, as the people.of God, cannot be "like castles in the sky", always talking about things out of time and space. That's right. Although theology sometimes sounds mysterious and difficult to discuss, personally, I have always believed in and experienced its impact on life, and thus am trying hard to narrow this imaginary distance between theology and life in the understanding of ordinary people. To do this, we must work hard to implement these truths of the Bible, so that we can experience them, as well as to constantly observe and reflect on the phenomena around us. God not only speaks through the Bible, but also through people and things that we encounter and through the Holy Spirit who lives in us.
