Christians are called by many names - some of them good and complimentary, and some of them, not so good or complimentary. We are called by several names in the New Testament.
Did you know that God thinks you are peculiar? Well, He does - - but not that He thinks you are odd or strange. For Him, it is not a critical term. And, in fact, He only calls us peculiar in the King James Version. Other translations use different words.
Who gave himself for us, that he might redeem us from all iniquity, and purify unto himself a peculiar people, zealous of good works. (Titus 2:14)
