Before He was crucified, Jesus prayed to God in the Garden of Gethsemane on our behalf. Christ’s suffering for our sins in Gethsemane and on the cross at Calvary is called the Atonement. He suffered for us so that we can be made clean and return to live with our Heavenly Father.
“For God so loved the world, that he gave his only begotten Son, that whosoever believeth in him should not perish, but have everlasting life. For God sent not his Son into the world to condemn the world; but that the world through him might be saved” (John 3:16-17 ).
