Sinful pride is self-elevation and self-love. That is in direct conflict with my "book."
Philippians 2.3 : Do nothing out of selfish ambition or vain conceit. Rather, in humility value others above yourselves
If I am guilty of this, I pray that the Holy Spirit convicts me of it. At the moment, however, I do not feel that I am looking down at others as worse than myself. I do believe the Bible is more TRUE than other books and also more important. However, I am not the Bible. I do not use the fact that I believe the Bible to make myself better by association.
I do question whether or not you, who do not even know me, can decide whether or not I am prideful. I am guessing you know some Christians in your own life who you see as prideful and assume I am just like them. That is called stereotyping, and it is not always a reliable source of information.
