John 8:
31 So Jesus was saying to those Jews who had believed Him, "If you continue in My word, then you are truly disciples of Mine;
32 and you will know the truth, and the truth will make you free."
Many Muslims will acknowledge the Jesus of the Quran who saves no one from their sins; but few will acknowledge the Jesus of the Bible Who is TRUTH HIMSELF (John 14:6), and sets free from sin all who continue in His word.
