Why Do My Arguments Not Convince Devout Believers?

I merely offer up good arguments against their faith. That's all I can do. Devout believers (my target audience) won't seriously consider them until such time as they have some sort of crisis in their lives that cannot be adequately explained by a good God. They'll seriously consider them at that time. My arguments are like seeds of doubt ready to sprout if and when they experience that crisis. Since many believers do experience some kind of crisis in their lives there will be a certain percentage of believers who, having been previously exposed to my arguments, will leave their faith at that time. It's a waiting game.
