It is impossible to put into words the full meaning of the Atonement, which is the most important and most transcendent event in the history of the world. Through His suffering in the Garden of Gethsemane and on the cross, the Savior atoned for our sins. This is the good news for all people!
We can't fully understand how Jesus suffered for our sins. But we know that in the Garden of Gethsemane, the weight of our sins caused Him to feel such agony that He bled from every pore.
Later, as He hung upon the cross, Jesus again felt the weight of our sins even as He willingly suffered painful death by one of the most cruel methods ever known. It seems, that in addition to the fearful suffering incident to crucifixion, the agony of Gethsemane had recurred, intensified beyond human power to endure. In that bitterest hour the dying Christ was alone, alone in most terrible reality.
The Savior tells us: For behold, I have suffered these things for all, that they might not suffer even as I."
Jesus Christ did what only He could do in atoning for our sins. To make His Atonement fully effective in our individual lives, we must have faith in Christ, repent of our sins, be baptized and confirmed by one having authority, receive the gift of the Holy Ghost, obey God's commandments, receive sacred ordinances, and strive to become like Him. As we do these things through His Atonement, we can return to live with Him and our Heavenly Father forever.
