Galatians 5:3 Again I declare to every man who lets himself be circumcised that he is obligated to obey the whole law.
Religion and Christianity may be seen as being the same by many, but there are subtle differences… Religion is based on laws and Christianity should be based on relationships.
Just as there were arguments back then, there will be many today as well. People will follow religion because it has a known set of laws and is easier to manage.
But if we follow the law, then we should follow the whole law and nothing but the law. Christ says otherwise. He asks us first of all to love Him and love each other, then adhere to the laws He has shown us, not those we make up!
