Actually, as a Christian I have thought of that very dynamic.
Christ said that he who denies me, so will I deny to my Father.
On the other hand, what if they day comes for me, where Christians are being fed to the lions. What if someone told me, "Deny Christ or we will rape, torture, and kill your children while you watch".
Do I refuse in order to guarantee my place with the Lord?
And if so, how does this reconcile with the command to "do unto others". I am quite certain that were I the small child on the receiving end of such an offer, I would want the denial to be done unto me.
Scylla or the Charybdis.
Bad or worse.
Such is the human condition.
