I am going to give you a very simple mental exercise I do when I decide if someone is a potential leader. Right, I want you to imagine it is Sunday morning and church starts in ten minutes. And something has gone wrong. There is a fight in the worship group that has turned vicious, and several members in the worship team are arguing over the song choices and it has devolved into a fight about who is the most (and least committed). It is turning nasty, voices are being raised and tempers are flaring up. You are utterly unaware of this because you are solving another problem in another department.
The person you are wondering about whether they are a potential leader is the first to arrive on the scene and arrives in the middle of the situation just as it is kicking off.
Now, will this person bring the situation to still waters and bring everyone to calm and peace and deal with the problem and make it smaller, or will they make it worse, causing the whole thing to blow up. Will they be someone who pours water on the fire or someone who pours petrol on it?
When you know if you want them to be the first person to show up, you know if they have potential as a leader in your community, church, business, etc.
If you grow those people you would want to be the first there if you could not be when there is a potential fire – grow those people – and you will grow the organization.
