Jesus said many good and absolute things. It is not about his words, but about his deeds. Words were also absolute, as well as deeds, because he could point at anybody and see his/hers heart. We are not capable of talking about concrete people because we do not see their hearts. Maybe that is the reason why Jesus did not write, he acted, healed, performed miracles. Words are universal, but his deeds are what make him God. When Jesus said you are healed, words did not heal you, but actions healed you.
