God understands how we feel because He also feels. Jesus expressed his feelings on different occasions.
! Matthew 12: 12-13: when he saw the merchants in the temple he became angry a lot and threw them out of there.
! Matthew 9:36: when he saw people who did not have God in their hearts,
He felt a lot of sadness and compassion.
! Matthew 26: 37, 38: When he was about to die he had many feelings. He
worried about his mother, he felt very lonely and abandoned, he felt the
physical pain and emotional pain.
