Having been on both sides of this, more or less (i.e., as a Baptist then a Jew), I can assure you, no matter which side of it you happen to be on, it's ALWAYS annoying to be told your religion isn't the "one true faith". :^)
If well wishes from an "apostate Christian" do not offend you, may God's blessings be upon you, and, of course "shalom".
