The verse below came up earlier in this thread. The NASB calls the Spirit of Christ a "he", indicating a person. The KJV calls the Spirit of Christ an "it", indicating that it's not a person.
One is obviously wrong but how do we determine which one is right?
1 Peter 1:11 New American Standard Bible (NASB)
11 [
a]seeking to know what person or time the Spirit of Christ within them was indicating as He predicted the sufferings of Christ and the glories [
b]to follow.
1 Peter 1:11 King James Version (KJV)
11 Searching what, or what manner of time the Spirit of Christ which was in them did signify, when it testified beforehand the sufferings of Christ, and the glory that should follow.
