Ezekiel 33:8,9. These verses should make every one of us tremble, when we realize how many professed Christians within the Church don’t bother to warn a soul of the coming judgment of God. It would seem that Paul had these verses in mind when he spoke of his responsibility to God and man (see Acts 18:6; 20:26,27). To help your hearers consider the seriousness of the situation (whether you are speaking to a crowd or just one person), you may like to say, “If you refuse to repent and you die in your sins, if your eyes and mine meet on the Day of Judgment, I am free from your blood because I haven’t held back from telling you the truth.”
Ezekiel 33:8 When I say to the wicked, ‘O wicked man, you shall surely die!’ and you do not speak to warn the wicked from his way, that wicked man shall die in his iniquity; but his blood I will require at your hand.9 Nevertheless if you warn the wicked to turn from his way, and he does not turn from his way, he shall die in his iniquity; but you have delivered your soul.
