Usually, we ask this kind of question, “how then can you say to me?” to a person who has levied some wild accusation against us. It is not a question but an answer to a baseless argument. The aggressive form of this question is “How dare you say that to me”. It conveys the meaning that the other person knows nothing about us. When Jesus prayed to His Father to forgive His killers, He prayed that they do not know what they were doing because they neither know me nor my authority. In a situation like a betrayal, we ask God that how could they do it to us. The simple answer is they did not know that we are His child. Often, we torment ourselves because we fail to remember that we are His children.
