The ability to lead make you a good leader. You don't need to have a straight character for you to lead people. You know why? No matter how yo act there will always be people that will say good or bad about your judgement. As a leader, you only need to do what is right even if it affects what you believe in or don;t reflect your character. However, we always see the opposite in our current leader. They will rather put themselves first before the masses.
No one is born a good leader, even though Leadership is your birth right. You grow into being a leader and that's training.
It might not necessarily be schooling, but learning under people who has learnt.
Yes you talked about having the ability.
Also leadership is influence
But what defines your ability and influence is character.
Making reference from The Creator's Manual :
Exo 18:21
https://bit.ly/BibleEN_kjvOne point talked about ability
Three points talked about character.
Finally, Leadership is not a display of superiority. It's functioning in the grace The Creator has placed on you.
