IMO, the bible does not teach stringent perfectionism. That’s why John 1:9 allows the sinner (saved by grace) to seek forgiveness when there’s been backsliding. J- seems to take scripture close to “stringent perfectionism” (which might not quite be what Jesus had in mind when he said on the cross, “Father, forgive them for they know not what they do.”)
There was certainly forgiveness. The first christians and missionaries to the Gentiles were Jewish.
However, on the whole, Israel has had a rough time of it for the last 2000 years, as they seem to have been driven from pillar to post in most Gentile nations, except the US. Now there’s growing animosity in the US, with many calling them Khazars instead of Jewish. Much of the reason might be how they seem to be able to siphon the wealth of the countries they’ve been to.
After Jesus had healed a crippled man at the pool of Bethesda, he said to the man, John 5:14
[SUP]14[/SUP]Afterward Jesus findeth him in the temple, and said unto him, Behold, thou art made whole: sin no more, lest a worse thing come unto thee.
Better to stay on the safe side of obedience, but not “stringent perfectionism.” Israel might be an example. (Romans 11)
Well, I don't believe a saint always stops sinning over night or even in a year or so. That is why 1 John 1:9 is there. But 1 Peter 4:1 says the believer can cease from sin. Galatians 5:24 says they that are Christ's have crucified the affections and lusts. Jesus told the woman caught in act of adultery to sin no more. If a believer could not stop sinning, then Jesus would have lied to this woman. For why tell someone to do something that they cannot possibly accomplish?
