For we do not have a high priest who cannot sympathize with
our weaknesses, but One who has been tempted in all things
as we are, yet without sin.
For the Law, since it has only a shadow of the good things
to come and not the very form of things, can never, by the
same sacrifices which they offer continually year by year,
make perfect those who draw near...For by one offering
He has perfected for all time those who are sanctified.
Hebrews 10:1, 14
and in Him you have been made complete...
He was perfect so we could be perfected.
