CAN WE REALLY BELIEVE WHAT THE BIBLE SAYS?

Yes for this two reasons:
God hates suffering a.nd injustice.
Consider how jehoveh God felt when his people in bible time were cruelly mistreated. The bible says that he was distessed because of "those who were treating them abusively". Judges 2:18
God has strong feelings about those who harm others. For example, the bible says that "hands that shed innocent blood" are detestable to him proverbs 6:16
Another reason is because God cares for us as individuals. Not only does each person know his own pague and his pain but so does jehovah ... 2chronicles 6:29
Through his kingdom, jehovah will soon end thr suffering of each individual. (Mathew 6:9) in the meantime he tenderly comfort those who sincerely look for him
