Here is a question that may or may not be relevant.
How many Chinese, have, "migrated," for one reason or another, into Canada, over the last 20 or so years? School? Other reasons?
You lack discernment. The Jews have played the harlot for a long time, that is true, but it WON'T last forever. So yeah, currently, they are lost, but that doesn't mean they will stay that way. They are lost to allow for the grace of God to come to the gentiles, THEN, Israel will be restored, but not because they were good, but because God made a promise. and He keeps His promises.
