Man's definition...
Sanity/Insanity depends on the moral structure of the community in which one presides....what is sane to one tribe, may not be sane to another tribe. This is according to abnormal psychology...
GOD'S definition:
2Ti 1:7 For God hath not given us the spirit of fear; but of power, and of love, and of a
sound mind.
That is why I love GOD...
Now HE has called us to be a peculiar people!
Tts 2:14 Who gave himself for us, that he might redeem us from all iniquity, and purify unto himself a
peculiar people, zealous of good works.
1Pe 2:9 But ye [are] a chosen generation, a royal priesthood, an holy nation,
a peculiar people; that ye should shew forth the praises of him who hath called you out of darkness into his marvellous light: 10 Which in time past [were] not a people, but [are] now the people of God: which had not obtained mercy, but now have obtained mercy.
