God left an instruction book for mankind, it's called His word. Also known as the Bible. If people followed the direction and principles within, the world would truly be a different place. Take the "golden rule" for example; if I did all I could to treat you well and make you happy, and you did the same in return,....we would both be happy! if everyone else did the same, ....you get the picture. The Bible has the answers. ..You need but sincerely want to know and make the effort to look.
