Odd is not the word for what's going on. If a person doesn't want to fuss over every aspect of The Lord's true identity and remain true to His PROPER name specified in scripture ("I am who I am", Exodus 3:14, He sent His only Son Jesus to die on the cross so that we would be eligible to return to Him), then they will not be able to recieve eternal life on the final judgement day. Allah did not die on the cross, therefore, salvation is exclusive only to Jesus as SAVIOR (Muslims believe in Jesus MESSENGER of their "god", clear difference). Jesus said that "...NO ONE comes to The Father but by ME" as SAVIOR, John 14:6.
There should be no arguement about this, it will not and cannot be changed. No one died on the cross except Jesus. No one sent Jesus to earth except His Father "I am who I am".
