This is so true. If you have a desire for knowledge in others things, more than the Lords Word; then you do need to examine yourself.
“Examine yourselves as to whether you are in the faith. Test yourselves. Do you not know yourselves, that Jesus Christ is in you?—unless indeed you are disqualified.” 2 Corinthians 13:5
Fact is, if there is anything in your life that you have more ‘passion for, zeal for, or knowledge of,’ than God (and His Word;) then it is an idol.
