Life is a journey. And if we share our journey with others, I believe the adventure can be even greater.
Jesus sent them out two by two, so let's share our life adventure together. I understand the journey or adventure can still be experienced by ones self. However, when we gather together, I think we can learn and grow from each others experiences.
After all, why not learn from those who have already been around the mountain - who knows how many times? Give opportunity to a wise man that again he may learn wisdom, and teach the righteous that he may progress beyond his teacher. Proverbs 9:9
