1 Corinthians 15:14,17
And if Christ has not been raised, then our preaching is in vain and your faith is in vain. And if Christ has not been raised, your faith is futile and you are still in your sins.

For so the Lord has commanded us, saying, “I have made you a light for the Gentiles, that you may bring salvation to the ends of the earth.”
Acts 13:47
