“but his blood will I require at your hand.” Although this is a specific revelation to Ezekiel, it has general application to every believer. The unsaved and ignorant do not know that people who are not saved will be destroyed in the Lake of Fire (Rev. 20:11-15), while people who are saved but live rebellious and disobedient lives will not have any rewards in the future Millennial Kingdom (1 Cor. 3:14-15; also, see commentary on 2 Cor. 10:5). It is the responsibility of people who are saved to do their best to warn the unsaved and disobedient about their upcoming fate and how to avoid it and have a wonderful everlasting future.
Jesus said to go preach the Gospel (Matt. 28:18-20) and called his disciples to be fishers for people (Mark 1:17). 2 Corinthians 5:20 says Christians are ambassadors for Christ. If believers warn unbelievers about the future but are ignored, the believers are not held accountable for the disobedience of others and in fact are rewarded for their evangelical efforts. If, on the other hand, believers stand idly by while unbelievers die in ignorance, God holds the believers accountable to some degree for not at least trying to save their fellow humans from everlasting death.
