Two are better than one, because they have a good return for their work. (Ecclessiastes 4:9).
Have you discovered yet that you are incomplete by yourself? During my "warrior" stage of life you would have been hard-pressed to convince me that I needed you or anyone else. I know few people willing to admit this, but many who live according to this principle. Sooner or later we discover God's truth regarding our need for others.
God made us to need others. We may not discover this until we fail -- fail in a business, a marriage, a close friendship, a client relationship. We are incomplete without the ongoing input from others into our lives. An independent spirit is one of the most detestable sins from God's viewpoint. It is the highest form of pride. "Pride only breeds quarrels, but wisdom is found in those who take advice." (Proverbs 13:10).
God has made each of us so that we have only so many gifts. He did not give you and me all the available gifts. He did this so that we will learn to depend on others and to humbly trust others to complete us where we are deficient.
David had Johnathan. Paul had Silas. John Wesley had George Whitfield. Martin Luther had Philip Melanchthon who was fourteen years younger. Martin Luther learned that he needed someone in his life to complete the work God called him to do. Luther had the greatest respect for this friend who helped him reform the church of their day, and the church as we know it at present. Luther learned a great deal from Melanchthon who was a great scholar at a young age. He could speak several languages, and he became Professor of Greek at the new University of Wittenberg at twenty-one years of age. This was ten months after Luther posted his famous theses on the church door in Wittenberg. Melanchthon helped shape the Protestant movement of the sixteenth century through his research, writings, moral purpose, and religious conscience. They became inseparable and when they died they were buried next to each other.
Who is that person God has placed in your life to complete you? Perhaps it is a mate. Perhaps it is a close friend. Perhaps it is a business partner. If you lack this in your life, I encourage you to seek someone out who can speak into your life. If you have someone like this, tell him or her how much you appreciate the role they play in your life.
