The title may be offensive to you. How could God’s word ever not work? Well, sometimes He doesn’t want it to. WHAT????
Matthew 13:10-13 And the disciples came and said to Him, “Why do You speak to them in parables?” 11 He answered and said to them, “Because it has been given to you to know the mysteries of the kingdom of heaven, but to them it has not been given. 12 For whoever has, to him more will be given, and he will have abundance; but whoever does not have, even what he has will be taken away from him. 13 Therefore I speak to them in parables, because seeing they do not see, and hearing they do not hear, nor do they understand.
