Honest rejection of Christ, ...

Honest rejection of Christ, however mistaken, will be forgiven and healed ... but to evade the Son of Man, to look the other way, to pretend you haven\'t noticed, to become suddenly absorbed in something on the other side of the street, to leave the receiver off the telephone because it might be He who was ringing up, to leave unopened certain letters in a strange handwriting because they might be from Him -- this is a different matter. You may not be certain yet whether you ought to be a Christian; but you do know you ought to be a Man, not an ostrich, hiding its head in the sand.

Quotes from the same author

The central Christian belief is that Christ's death has somehow put us right with God and given us a fresh start. Theories as to how it did this are another matter. A good many different theories have been held as to how it works; what all Christians are agreed on is that it does work.

Emeth came walking forward into the open strip of grass between the bonfire and the Stable. His eyes were shining, his face was solemn, his hand was on his sword-hilt, and he carried his head high. Jill felt like crying when she looked at his face. And Jewel whispered in the King's ear, "By the Lion's Mane, I almost love this young warrior, Calormene though he be. He is worthy of a better god than Tash.
You will not find the warrior, the poet, the philosopher or the Christian by staring into his eyes as if he were your mistress: better fight beside him, read with him, argue with him, pray with him.
The poison was brewed in these West lands but it has spat itself everywhere by now. However far you went you would find the machines, the crowded cities, the empty thrones, the false writings, the barren beds: men maddened with false promises and soured with true miseries, worshipping the iron works of their own hands, cut off from Earth their Mother and from the Father in Heaven. You might go East so far the East became West and you returned to Britain across the great Ocean, but even so you would not have come out anywhere into the light. The shadow of one dark wing is over all Tellus.
