One of my favorite things about working in ministry is building lasting and authentic relationships. As God blesses you and expands your territory, there are blessings and challenges that come with each new adventure. If you are being led by God to expand into new territories, I celebrate with you what God is doing in your life. I've learned from the Bible, my parents, and mentors in my life that what God has for you is for you. Therefore, why feel threatened and/or insecure about God's movement in another person's life when He has plans to prosper your life as well.
I encourage you to carry in your spirit the words of Michael Jordan, who said, "Talent wins games, but teamwork and intelligence win championships."
