Leading entails influencing people to think, say and behave in ways that take them from one place to another. Leading can be formal (you hold a position of authority in a group) or informal (you influence people but don’t hold a position of authority).
Use your retirement to find your “why” in Him. Allow God to use your commitment and abilities, and the wisdom you have gathered to achieve God’s purpose for you. God reminds us that if he has called us, he will be with us till the end. (Isaiah 46:4)
