Even as we need natural fathers to guide us in our early years of life so also we need spiritual fathers who will nurture our faith in God. This is not an easy task, it takes prayer, time and patience. But it is a quality investment of your time. It is allowing close someone from the outside that God has brought near for you to mentor. The Apostle Paul said, "the older is to teach the younger." Though sometimes it is the older in the faith and not in years.
In the span of time our lives are very short, what legacy will you be leaving those who know you? There is a poem by Sam Walter Foss entitled, "House By The Side Of The Road," I encourage you to read it. Part of it reads, "Still I rejoice when the travelers rejoice, and weep with the strangers that moan. I will not live in my house by the side of the road like a man who dwells alone." Paul said that we do not live to ourselves and we do not die to ourselves, we are connected to God and to each other.
Selfishness is a lonely life and a terrible waste of that gift. For those of us who know Him, we are to pour our lives into others around us and as we do, every once in a while, God will send someone special. He will send that one He has just rescued and placed His Spirit in. You will recognize them by their wide eyed innocence and hunger for all things God. It is then that they need you, a "Father (or mother) in the Faith."
