Jeremiah was commanded by God to preach even though He knew they would not listen.
Noah preached 120 years when no one would listen in all those years, he continued to built the ark God commanded. Many of those people who drown in the flood after God closed the door of the ark were Noah's relatives.
We are commanded to speak truth in these last days even if no one will listen, even if they hate us and even if we do not see one convert. The time is at a close there will be few converts compared to the population of the world.
American has grown cold to the Word of God, loving its pleasure more than God.
