@Goodlife - Every religion that evangelises uses that same redundant rationale. Christian missionaries used that same argument when they go on their missions to the ungodly. Mormons the same. JWs are an active case in point.
That argument is arrogant and specious. It assumes that your particular flavour of religion is true in all its evidence free assertions and assumptions.It arrogantly assumes that people should be treated like incompetents or children - unable to make up their own minds and needing "guidance" from the wise and patient evangelists.
The argument in favour of such evangelical initiatives is to bring enlightenment to the masses, so they can enjoy gods grace - but that implies that god is like a commercial entity, a company, concerned only about his own customers, and only wiling to offer the benefits of his bounty to those signed up.
If your god is as loving and caring as you proclaim, then he would judge everyone on the merits of the way they lived their life - not simply whether they had been contacted and had signed up as a customer. Its a nonsense argument.
If you want to reach out to potential converts, confine yourself to the internet and mailshots - stop trying to badger people into converting. Its no accident that those most likely to convert as a consequence of such a visit are those most vulnerable to such unethical doorstepping.
