You cannot "mind your own business" because if you do you leave the doors open for the evil-minded to unite and crush those like you. You have a duty to God to uphold His values because He died for you, and if you do not repay this absolute sacrifice, you are damned to suffer for eternity. Freedom can only be found in Christ, because if you are "minding your business" being a slave to your passions, then you are not being free, and only being enslaved by the evil-minded seeking to profit from your folly.
