He said, "No, father Abraham, but if someone goes to them from the dead, they will repent!" But he (Abraham) said to him, "If they do not listen to Moses and the Prophets, they will not be persuaded even if someone rises from the dead." Luke 16:30-31
This verse contradicts whole movements in apologetic* circles. Facts aren't the problem. Unbelief is the problem. Getting into a fact-war with an unbeliever will only allow him/her to hide their unbelief. Facts are useful and glorious, but only in the context of certainty. We don't give up the certainty of God's existence and then try to prove Him with facts. On the contrary, we use facts to indict the thinly-veiled unbelief.

*Apologetics means defending the faith.
