God desires His Word preached as a witness to all nations, but He controls whom He calls and chooses among those who hear it. He will give the rest an opportunity for salvation in the second or general resurrection from the dead (Revelation 20:11-13). Among those will be many atheists who could see no worth in believing a God who did not respond to them or in a Christianity that did not live up to its principles. At that time, many of them will finally have their eyes opened to believe the truth and submit to Christ.

It is not the job of the church to convince unbelievers out of their unbelief with clever apologetics or emotional appeals. Instead, its job is to preach the truth of the Bible with conviction and clarity, live it as much as possible before the world as examples of Christ's way, and be prepared to assist those whom the Father calls and leads to Christ and His church. That is enough for human beings coming out of this world, even with the help of the Holy Spirit. We can leave the rest to God.
