Not very sure about this khazar thingy, but what I am sure about is that this flattering towards and even idolizing of jews and "the state of Israel" is certainly not from God. It is a delusion and heresy that crept in primarily by way of dispensationalism but also through ecumenical efforts. We are to love jews by telling them the truth, which means giving them the gospel. And some jews have repented from unbelief and trusted Christ. And let's be honest and balanced; there are plenty of gentiles in the whole world who also need to repent and trust Christ. We're not into this because of mere worldly politics, it is about making Christ known to the unbelieving and dying world of jews - and gentiles.
