عُدتُ الى المنبر هذه المرة لأبشر بالمسيحية +++

Yes I agree, but at his time
He was addressing the Jew and telling them I am the way. He is right he is the only way to GOD at that time and the Jew ought to accept him
Muses (PBUH) was the only way to GOD at his time, all prophets were the only way to GOD at their times and according to the capacity that they had
According to the Christian logic. The people before Jesus (PBUH) , have no salvation. Because the did not get the Chance to accept him. But in Islam we believe that GOD sent to any nation before Mohammed (PBUH) a messenger, and they should accept him, and there are no missing parts in the prophet-hood chain
Jesus himself tells that he has many things to be said. But the people at that time can not take it. That means another prophet will come and he has the capacity of implementing the last message

Also I want to say that I did not break the context, there,because I did not quote the verse number 22

Quote: 21 “Not everyone who says to Me, ‘Lord, Lord,’ shall enter the kingdom of heaven, but he who does the will of My Father in heaven. 22 Many will say to Me in that day, ‘Lord, Lord, have we not prophesied in Your name, cast out demons in Your name, and done many wonders in Your name?’ 23 And then I will declare to them, ‘I never knew you; depart from Me, you who practice lawlessness!’
