Aaron's leadership style was to satisfy the people. When the people approached him with a problem, Aaron didn't consider God's wishes. Instead, he tried to satisfy the people's desires. Not succeeding, he simply "let the people run wild" (Ex 32:25). Under Aaron's weak "leadership," sinfulness, chaos, and confusion reigned instead of godly order (see 1 Cor 14:33, 40).
Diotrephes, an early Christian leader, "enjoyed" being a Church leader (see 3 Jn 9). He loved to dominate (3 Jn 9, RNAB). His leadership style apparently consisted in trying to satisfy himself. Diotrephes is not presented in Scripture as seeking to determine God's wishes. Instead, He arbitrarily refused to acknowledge Church authority established by God and expelled those who wished to submit to it (3 Jn 10).
Moses was a true servant-leader (see Lk 22:26). He exercised his God-given authority as needed (Ex 32:26), but typically was meek (Nm 12:3) as he listened to his people's needs (e.g. Ex 18:13). His leadership style was to satisfy God and sacrificially love his people. He constantly sought God's direction as he submitted his leadership to God (Ex 34:34). He interceded on behalf of his beloved people, even if he might have to suffer because of it (see Ex 32:10-14, 32).
Is God calling you to be a leader? Seek God's wishes. Answer His call. "With a leader to break the path they shall burst open the gate and go out through it" (Mi 2:13).
