A successor needs to love us, not what we do, or what we get paid. Our successor must love us and love what we love. Jesus chose 12 men who loved what He loved and hated what He hated. When asks one of them replied, "Where would we go? You have the word of life." Once we are convinced that our leader/leadership is hearing from God and following to the best of their ability it become easier to love and follow their lead.
"And the things that thou hast heard of me among many witnesses,
the same commit thou to faithful men,
who shall be able to teach others also."
