Who Has the Duty to Proselytise?

According to Ray Comfort of Living Waters: every Christian.

Here is where he said so:

THIS Is Why I Hate Prosperity Preaching.

And he used, to begin with, two arguments. 1) An analogy. 2) A Bible quote or more than one.

1) "If you have a rope at your feet, and there is a man drowning and you could save him, and you just stand there and do nothing ..."

How far out is the drowning man, how far out can I through the rope with a lifebuoy on it?

If I am too weak, I hope someone comes around who's stronger and likelier to reach out?

And if I didn't wait, the buoy would not actually reach him, he would still be drowning, and I would have wasted the opportunity for someone stronger than myself to save him.

If he's already sunk, and I am no diver?

There are indeed situations where not saving a drowning man would be held excusable.

So, if the man is three yards off the bridge and I can through the buoy that far, perhaps I do throw the buoy. But if he's five yards off the bridge, I may be better off waiting for someone else to throw it. Meaning, obviously, hours when it is likely someone else may turn up reasonably soon.

If there isn't, I am obliged to throw as far as I can and yell to the drowning man to do an effort of swimming to the buoy. But I am not obliged, unless well trained and not weakened, to actually swim out with the buoy.

By the way, don't hire Ray Comfort as legal council, the crime is not called "depraved indifference" it's the name of a disposition constitutive (but not on its own) of a few crimes:

In United States law, depraved-heart murder, also known as depraved-indifference murder, is a type of murder where an individual acts with a "depraved indifference" to human life and where such act results in a death, despite that individual not explicitly intending to kill. [...]

If no death results, such an act would generally constitute reckless endangerment (sometimes known as "culpable negligence") and possibly other crimes, such as assault.

"If you see someone getting into a car, and it has no breaks and you know that ..."

What if the person entering the car entered and started the car too quickly for you to warn him? What if you thought he was getting a key from it and didn't know he intended to go for a ride in it?

Are you obliged to stand by the car and warn everyone?

2) Whom we preach, admonishing every man, and teaching every man in all wisdom, that we may present every man perfect in Christ Jesus.
[Colossians 1:28]

"We" refers to St. Paul and those who were his fellows in the ministry. And their successors, clergy. Not each and every Christian.

If, when I say to the wicked, Thou shalt surely die: thou declare it not to him, nor speak to him, that he may be converted from his wicked way, and live: the same wicked man shall die in his iniquity, but I will require his blood at thy hand.
[Ezechiel 3:18]

Ezechiel was a prophet and this was the rule for prophets. Not each and every Christian is a prophet and those being prophets about the Biblical content of warning are the clergy.
