John 12:37 Even after Jesus had performed so many signs in their presence, they still would not believe in him.
Don't get up tight about people not believing you when you talk about Jesus – just tell them the truth as you know it.
Jesus told the people the truth and even showed them through miracles what would and could happen...
Yet many still chose not to believe in Him. Just do you best to tell the truth and allow Christ to work in their hearts instead.
