Oh no! Not the beep beep analogy again.

Please, make it stop! As for the sins and payment thereof, we actually believe he began to pay for them in the Garden and completed payment at the moment he died on the Cross. And we worship the same Jesus you do; we just disagree as to the exact form he takes in relation to the Father.
It must make a valid point if it bothers you .
Ezra Taft Benson, current prophet of the Mormon Church, explained the Atonement for Mankind's sins happened in the Garden of Gethsemane.
"What happened in that garden, said President Ezra Taft Benson, `was the greatest single act of love in recorded history.
"`It was in Gethsemane that Jesus took on Himself the sins of the world, in Gethsemane that His pain was equivalent to the cumulative burden of all men, in Gethsemane that He descended below all things so that all could repent and come to Him.'"
He continues by stating, "`That holy, unselfish act of voluntarily taking on Himself the sins of all other men is called the Atonement'" (LDS Church News, 1 June 1991, p. 14).
This doctrine seems to have been getting toned down somewhat in recent years by the LDS Church, probably in an attempt to make the Church appear more like a mainstream Christian denomination. This is illustrated in recent editions of the official LDS Church book Gospel Principles.
The 1978 edition of Gospel Principles puts the focus of the atonement on Gethsemane:
"In the Garden of Gethsemane, Christ atoned for the sins of all mankind." (Page 58,)
At the cross it is simply stated that Jesus died there:
"Christ died on the cross at Calvary." (Page 58,)
The 1997 edition of Gospel Principles now seems to be drawing away from the focus of Gethsemane and is putting greater emphasis on the cross:
"In the Garden of Gethsemane, the Savior took upon himself the sins of all mankind." (Page 58)
The sentence about the cross has now been expanded to include the words "our sins":
"Jesus died for our sins on the cross at Calvary." .
Christians do not believe that Christ atoned for our sins with the blood (if it was indeed blood) that fell from Him at Gethsemane. The scripture actually says Jesus sweat was "like" great drops of blood. It does not say it was blood.
To Christian, the cross is absolutely central to the atoning work of Jesus. The whole point of Jesus death was to atone for our sins, as the animal sacrifices made in Old Testament were to atone for the sins of the people at that time. These sacrifices pointed towards Jesus ultimate atonement, death, and sacrifice.
The major focus for Christians is the cross of Christ, and His atonement for our sins there. The lack of focus upon the cross, in Mormonism, is may be one of the reasons why there is not a single Christian cross anywhere, in any Mormon temple in the world.
