God has not called us to save America; He has called us to save Americans from the coming judgment of God by introducing them to faith in Jesus Christ.
Jesus clearly taught that the majority of humanity will spend eternity in hell, and only a few will find the exclusive way to salvation.
Unlike many people today, Jesus did not teach that all religions in the world are simply different paths up the same mountain of truth that leads to God. Jesus could not have been more clear: he offers the only way to heaven.
When commanded by the Jewish officials to quit invoking the name of Jesus Christ, Peter responded, "And there is salvation in no one else: for there is no other name under heaven that has been given among men, by which we must be saved" (Acts 4:12). Remember, Peter was a Jew, speaking to a group of Jews, claiming that there is no salvation for Jewish people - or anyone else - apart from faith in Jesus Christ.
If the universalists are correct in saying that everyone is going to be in heaven regardless of what they believe, or the pluralists are correct that all religions lead to the same god, then the horrific death of Jesus Christ was completely unnecessary.
If all, or the majority of humanity, end up in heaven, then Jesus made a mistake in his pronouncement that only a few will enter through the "narrow gate" into heaven. And if Jesus was wrong about this, then one could assume that he may have been wrong about a number of other issues of which he spoke.
We're in danger of losing an even more foundational belief of Christianity: that salvation is only possible through faith in Jesus Christ.
One of the consistent themes you'll find throughout the Bible is that God will always provide the necessary information about Jesus Christ to someone who sincerely desires to receive that revelation.
The cross of Jesus Christ represents the intersection of God's love and God's holiness.
Those of us who are Christians believe Jesus Christ is the only one who can redeem us.
