Except that that's not what the Scripture states, and calling God the "pillar and ground of truth" is demoting God. God is truth personified.
Proverbs 9:Wisdom hath builded her house, she hath hewn out her seven pillars:
2 She hath killed her beasts; she hath mingled her wine; she hath also furnished her table.
3 She hath sent forth her maidens: she crieth upon the highest places of the city,
4 Whoso is simple, let him turn in hither: as for him that wanteth understanding, she saith to him,
5 Come, eat of my bread, and drink of the wine which I have mingled.
6 Forsake the foolish, and live; and go in the way of understanding.
7 He that reproveth a scorner getteth to himself shame: and he that rebuketh a wicked man getteth himself a blot.
8 Reprove not a scorner, lest he hate thee: rebuke a wise man, and he will love thee.
9 Give instruction to a wise man, and he will be yet wiser: teach a just man, and he will increase in learning.
10 The fear of the Lord is the beginning of wisdom: and the knowledge of the holy is understanding.
Say what again about demoting God...take a look again at verse 10?
Also note the mention of wine and bread again in this Proverb.(the wine and bread freeper dialogs are agin being mentioned in this thread) What does Christ call himself but the “Bread of Life”? Proverbs 9:1-10 is a description of the word of God made Flesh, the man Christ Jesus!
And if God be Truth Personified, is he not the author and finisher of our faith, our rock we stand upon? Everything we are as people are sourced out of God, for it is “In him we live and move and HAVE our being”!
