God doesn't speak of any other nation in the context of last days as much as the nation of Israel. This highlights the key role of the Jewish people in the last days, which have already begun. God is ready to water every small seed we sow into the Jewish people that may seem insignificant and weak to us.
We think it is a drop in the sea. But this drop changes the quality of the vast waters of the sea into which it fell. So, do not hesitate. Do not be afraid or embarrassed for sowing these seeds depends on us. And with each drop of grace, God is able to grow from this mustard seed of faith and deeds such a tree that will give shelter to the birds.
