When I was very young, my grandfather already started telling me some of the rules of life he had learned which he thought would benefit me too in my life. As I grew up, I began to learn many more rules from my own life experiences. Later, after I came to know Christ, I had to discard or modify many of them. I now see one rule that a Christian must follow, that is, no matter what I contemplate doing, it must be according to God's will. Naturally, I am excluding the usual routine chores; I am talking about the more unusual ideas that pop into my mind. It is easy to brush God aside and follow your own intention. Therefore, the rule is to make sure that whatever we attempt to do, we are prompted by the Holy Spirit. The sign that we are following God's will is that we'll have inner peace.
