Luke 22:41-44 Jesus' atonement for mankind

                                                      Del Parson Prayer At Gethsemane

⁴¹ And he was withdrawn from them about a stone's cast, and kneeled down, and prayed,
⁴² Saying, Father, if thou be willing, remove this cup from me: nevertheless not my will, but thine, be done.
⁴³ And there appeared an angel unto him from heaven, strengthening him.
⁴⁴ And being in an agony he prayed more earnestly: and his sweat was as it were great drops of blood falling down to the ground. -Luke 22:41-44 Bible, King James Version

It is believed by mainstream Christians that Jesus atoned for the sins of all mankind past, present and future. This does not appear to be supported by the Teachings of the Ascended Masters although there is a degree of Truth in this concept. Beloved Jesus teaches us: "I came in those centuries long ago to take away a certain proportion of the hatred of the world. I consumed that hatred. I have poured Love to take its place." ('The I AM Discourses' p225) Also Beloved Saint Germain sheds more light on this subject: "Then remember your Beloved Master Jesus... He gave His Life to take away the hate which was destroying everybody and everything at that time on the Earth. It would have completely destroyed the Planet, if His Light had not come, taken away the hate and given His Life, His Sacred Fire Love in the place of the hate, so the World might be sustained."('The Voice of the I AM' 1952 April p9)

...[2] Something may here be said about the Lord's work of salvation. It is known in the church that the Lord is the Savior and the Redeemer of the human race, but it is known to few how this is to be understood. They who are in the externals of the church believe that the Lord redeemed the world, that is, the human race, by His own blood, by which they mean the passion of the cross; but they who are in the internals of the church know that no one is saved by the Lord's blood, but by a life according to the precepts of faith and charity from the Lord's Word. They who are in the inmosts of the church understand by the Lord's blood the Divine truth proceeding from Him, and by the passion of the cross they understand the last of the Lord's temptation, by which He completely subjugated the hells and at the same time glorified His Human, that is, made it Divine; and that thereby He redeemed and saved all who suffer themselves to be regenerated by a life according to the precepts of faith and of charity from His Word. Moreover, by "the Lord's blood" in the internal sense, according to which the angels in the heavens perceive the Word, is meant the Divine truth proceeding from the Lord (n. 4735, 5476, 6978, 7317, 7326, 7850, 9127, 9393, 10026, 10033). [3] But no one can know how man was saved and redeemed by the Divine through the subjection of the hells and the glorification of His Human, unless he knows that there are with every man angels from heaven and spirits from hell... and thus that in respect to his interiors man is either under the dominion of spirits who are from hell, or else is under the dominion of angels who are from heaven. When this is first known, it can then be known that unless the Lord had wholly subjugated the hells, and reduced all things both there and in the heavens into order, no one could have been saved; nor likewise unless the Lord had made His Human Divine, and had thereby acquired for Himself to eternity Divine power over the hells and over the heavens. For neither the hells nor the heavens can be kept in order without Divine power, because the power by which anything comes forth must be perpetual for it to subsist, for subsistence is a perpetual coming forth. [4] ...the Lord then came into the world and... saved and redeemed man through faith and love to the Lord from the Lord; for such the Lord can withhold from the hells and from eternal damnation, but not those who reject faith and love from Him to Him, for these reject salvation and redemption...

Last Judgment, by Emanuel Swedenborg, [1758], tr. by John Whitehead [1892], at sacred-texts.com

10. II. ...It was said to me from heaven, that the human race on this earth would have perished, so that not one man would have existed on it at this day, if the Lord had not come into the world, and on this earth assumed the Human, and made it Divine; and also, unless the Lord had given here such a Word as might serve for a basis to the angelic heaven, and for its conjunction.

                           Violet Consuming Flame: God's Gift to Man

This Gift does not cleanse us from all our past mistakes. In order to do so we must use the Violet Consuming Flame. The Beloved Jesus teaches what He meant by Grace: "Now because of the Great Master Saint Germain's Use and Release of the Violet Consuming Flame, which was the "Grace" that I taught, mankind have been given the Way and Means of consuming their mistakes. If an individual has created discord thru mistakes of the past and in the Full Acceptance and Authority of the "Mighty I AM Presence," will call on the Law of Forgiveness, use the Violet Consuming Flame to dissolve and consume all that has been less than Perfection, then Life once again opens the Pathway into the Realm of Perfection!"
