Partaking has nothing to do with "forgiveness of sins" thats not scriptural.
The new Covenant is with Mankind in General.
Holy Spirit and being "annointed" simply means access.
Access to God directly, "I will pour out my Spirit on all flesh;" Joel 2:28
ALL people:
"For Christ is the end of the law for righteousness
to everyone who believes" Romans 10
Everyone who believes is annointed, its not a special group or "class"
this is the fundamental ERROR.
Partaking is about being part of the Body of Christ.
Its Universal, free, by Grace and open to all believers.
There IS no "special class" called "the annointed" set apart from all believers,
this error and belief in an "annointed class" is embedded in you
so deep, by the Watchtower you keep going back, to the magical eight men,
with hushed voices of awe. Freedom is seeing that there everyone
is annointed by belief and faith and Grace.
