Luke 7.

„30But the Pharisees and experts in the law rejected God’s purpose for themselves, because they had not been baptized by John.”

There are some reasons why people can reject God’s purpose. It can be the kind of pride that does not allow to accept other teachings and harden a heart but it can also be the thought that you are not worth enough to receive God’s promise. But it also can be assumed that the person does not believe that Jesus love is so great to forgive or that his power is too little to help such a lacking person. The Pharisees here did not only reject it but also despise it (German). Therefore God was not able to give them what he wanted them to receive.
