God made promises to Abraham (Gen.12:1-3, 17:7) & his’ Descendant/The Seed‘ (Christ, the Messiah) but the Jews stumbled on this (Isaiah 28:16, Rom. 9:33), they misinterpreted it & took it as it was just for all Abraham’s descendants in the flesh, Israelites. Sadly they still believe that today! Most of them believe in salvation because of their race. But we’ll talk about this on a next post ‘Who is Abraham’s Seed‘.
All through out John chapter 3 we notice so many times that salvation if for whosoever believes in Jesus Christ. The King James translates the Greek word ‘pisteuōn‘ in ‘beliveth‘ to indicate the verb is in present progressive ‘believing‘, the action still continues.
