o.k. so, have you kept every statue set forth in the Sermon on the Mount since conversion? have you known to do good and done so all day each and every day since conversion? if that answer is no ( hint- it is. for everyone, including you ) then you are not sinless!
This kind of spirituality is God expected Israel to obey the law and if they failed
in one point, they were to die.
But God expected them to follow the law and be careful not to break anything.
If they did they were to repent and offer a sacrifice for the sin atonement.
Nothing has changed in the new covenant, equally we are expected to obey,
and if we discover we have failed to repent confess and accept the sacrifice Christ
gave on the cross. God never said we would not have trials and failures, he showed
us through His people we would, but if we believed in Him He would bring us through
through repentance and faith.
These guys must really hate Gods ways the way they oppose and preach so obviously
against His precepts and resolutions to cope with our frailties. The Lord differentiated
between rape and non rape, murder and accidental killing, providing cities of refuge.
These legalists have no insight or shame, no humbleness or grace, it is the letter of the
law or nothing, lawlessness with a covering of Christs righteousness so nothing we do
matters anymore. It is such a contradiction they cannot agree among themselves how
it works, let alone is it sane or just.
