How do Muslims take things out of context?
By cherry-picking verses and ascribing properties to them that are non-existent. It's as ridiculous as when non-Muslims try and take verses from the Quran and make them say something that no Muslim would ever believe they are saying.
Are you not taking what Jesus said out of context when he said "why do you call me good?" by comparing what he said there with something else he said at another time in a completely separate conversation?
Do you not think that Jesus was consistent in the things he said? He said, in various places, that he was the good shepherd, that he and God were one, and that he had been with God from the beginning. There is nothing in scripture where Jesus ever denies that he is God -- only statements from him that showed that he was. In the context of all this, for him to say, as you believe, that he is not good is completely at odds with everything else he said. But Muslims take this one verse, decide on an interpretation of it that suits them, and promote it to the exclusion of the rest of the Bible. It makes no sense, and when someone like me who knows the Bible reads it, it's very hard not to just laugh.
A Christian who knows the Bible can read that verse and not think for a minute that Christ is denying that he is good because we know the other statements that he made about himself. So we read that verse, correctly, as Jesus saying, "If you are calling me good, and only God is good, are you not admitting that I am God?"
If I were to mash up a bunch of different quotes from you, from completely different posts and use them to say you said something and this is what you meant by it, you would say I'm twisting your words, so why do you do that with what Jesus said?
If you can find something I have said about myself that completely contradicts everything else I have said about myself -- which is what you are saying that Jesus Christ did when he said that only God was good -- then you will have proved your point. So please, be my guest.
