Judgment for sin occurred at the crucifixion of Christ in both the material and spiritual planes.
In our bodies, we experience immediate and temporary (physical lifetime) effects of living apart from God. In our "souls", we realize "grief" (as your Scripture reference states) that is both immediate and can be permanent (our choice).
This is the "forsaken" that Jesus willingly bore for us (if we choose) on the cross. If we decline, it is our abandonment to bear.
Really?? So what are the two laws for that are given in the NT? Repenting of sins is done through (sincere) prayer these days (since Luke:21:24) What was 'set aside' was the 600+ morality and diet laws and that officially ended when Peter had the vision in Acts:10 which would have been 3 1/2 years after the cross, the end of the 70 week.
Grief was fulfilled when Jesus said those words. If people were free of sin they would be free from judgement, the Gentiles have yet to be judged and that happens when the bruise to Satan's head happens. (as in the sheep/goats judgment from Matthew:25) and feeding the poor is the dividing line so most \Christians' will fail on that score alone. It doesn't mean feeding the poor of the congregation, it means feeding a hungry stranger.
M't:5:43-47:
Ye have heard that it hath been said,
Thou shalt love thy neighbour,
and hate thine enemy.
But I say unto you,
Love your enemies,
bless them that curse you,
do good to them that hate you,
and pray for them which despitefully use you,
and persecute you;
That ye may be the children of your Father which is in heaven:
for he maketh his sun to rise on the evil and on the good,
and sendeth rain on the just and on the unjust.
For if ye love them which love you,
what reward have ye?
do not even the publicans the same?
And if ye salute your brethren only,
what do ye more than others?
do not even the publicans so?
This is when that last sentence in your post was determined rather than on the cross.
Proverb:8:336:
Now therefore hearken unto me,
O ye children:
for blessed are they that keep my ways.
Hear instruction,
and be wise,
and refuse it not.
Blessed is the man that heareth me,
watching daily at my gates,
waiting at the posts of my doors.
For whoso findeth me findeth life,
and shall obtain favour of the LORD.
But he that sinneth against me wrongeth his own soul:
all they that hate me love death.
