On Good Friday, 2,000 years ago, He suffered and died for our sins.
It wasn't just the three hours during which He hung on the Cross. It was all day, from Pilot, to the scourging at the pillar, to the carrying of the cross, to His death. He suffered all day because of what we have done.
"For God so loved the world, as to give his only begotten Son; that whosoever believeth in him, may not perish, but may have life everlasting." John 3:16
