This I find, is hard for Ephraimites generally, to accept, and Judaism is sometimes 'overboard' on it - and in saying the latter, I obviously reveal my own roots in Ephraim, or said plainly, my previous contamination by Christian dogma. It seems that much of our religious misunderstanding and hypocrisy is rooted in religious people's endeavours to be 'spiritual' only - rather than 'human' or both. A perfect Israel will only come beyond the Gates to the Kingdom - not before. In the mean time we have to live in true compliance with His Divine Requirements. This means, I believe, that at its pinnacle, it should be motivated and lived from within His nation and Land.
Perfection is a process to achieve and to create, by correct and exemplary living.
It is not a platform to join, when it comes around our way. Until, one day not so long ago, I tried to find such a Command in the Torah. If we wait for the majority to be faithful, it will never happen. Teshuvah qualifies us for spiritually belonging to His Kingdom. Physical conversion is belonging physically to His nation in this anti-Jewish world, like every 'born' Jew out there.
