The idea that God sat in Heaven unmoved by the events on the cross is unthinkable. He bore the pain of Christ's sacrifice in a desire to show us His love. We have a hard time grasping the depth of God's love because all we have seen is human love. We are well aware that we live in a day of no-fault divorce. People get married and they get divorced.
Love is strong and then it seems to disappear.
Human love is fickle. They are the fans who root for a team only when they are doing well. We've watched children as they seem to alternately love and then hate their friends depending on how useful the friends are at the time. But God's love is not like this. In Matthew 25 Jesus tells those who are His followers to receive the Kingdom which God prepared before creation.
