So since it is in the Bible, and the Bible said all human are sinners and the Bible also said that only few are God's children, THEREFORE we are equal in God's because we are sinners??? See where I'm going here?
As human being we are equal to God because all human are sinners.
If you are talking about the love of God, then we are equal because God loves all sinner.
But you mentioned that we are equal because we are all His children. Never in the Bible mentioned that all are God's children.
Ikaw, sa tingin mo be we are all equal before God's eye because all human are His children?
