 God still has a reason for everything that allows in our life. So salt normally prevents decay and rot and corruption, but also it seasons. But also salt makes thirsty. So what do you mean? As a Christian, if we are the salt of the earth, we will make lost people thirsty for what we have. Jesus said, I'm the living water. If you'll come and drink of my water, you'll never thirst again. As if we're salt, we're making lost people thirsty.
