“A leader is one who knows the way, goes the way, and shows the way.” – John C. Maxwell
Honestly, I did not have a quote from memory and just searched the internet. However, when I came across this quote, it certainly speaks to me. I have always believed one should do as s/he says. For instance, I never give advice to my kids that I do not follow myself. If I were to find something that would contradict my own behavior, I use it as an opportunity to learn and grow before I can truly encourage them on that path. As for the above quote, I really center on the second half: "goes the way, and shows the way." It certainly is important for a leader to 'walk the walk.' By that example of living in the manner you want a congregation, for example, for live, it demonstrates to them, by a living example, how to do so. In the context of a church community, it is important for ministers to try to live the love Christ exemplifies, so that others take witness and learn how to do so themselves by seeing the example set forth.
On a deeper level, Jesus was our leader in this manner. God certainly "knows." He incarnated Himself as Jesus to 'go the way' and live the love of God and neighbor. In doing so, Jesus became our example by 'showing us the way' in how He faced a variety of challenges, societal or internal.
