it's hard to say that God will forgive all your sins before you apologize to the person you have hurt, because it relates to the rights of fellow human beings,

because one of the conditions for getting God's forgiveness is to get forgiveness and willingness from the people we have hurt,

if the sin is related to the rights of fellow human beings. but after they forgive us God will also forgive us ... because of the God of love and forgiveness of sins..
