Then don't give them any reason to confirm their suspicions - keep the commandments and they'll see that in a world full of weak, whining, hypocritical, presumptuous OSAS License to Sin holders, there are genuine, faithful, obedient, true Christ followers who keep the Ten Commandments just as Jesus kept them.
And, according to Scripture, they'll "see your good works and glorify your Father which is in heaven" instead of being strengthened in their iniquity by those who "refuse to turn the wicked from their evil way by promising them life" - Ezekiel 13:22 KJV
But you have no life to offer do you ... if you did that would be your message

When you set yourself as judge over God's people, there is no such ministry in the church, that was OT, they had the law therefore they must needs have judges to to apportion blame and administer the penalties for every breech of the law.
But you have set yourself up as judge, you are claiming you are perfect, without sin for only one who is perfect can judge.
Thou shalt love the Lord thy God with all your heart and mind and strength but you do not and yet upon this, and the other. love thy neighbour as thyself, which also you do not, hang ALL the law and prophets. You see by this how hopeless your case is.
The law holds a mirror up so you can see yourself but it has no power to change your image, the purpose of the law is to make you flee to God for mercy.
That's what we did ... and we found it too.
