In the book of Proverbs, Lady Wisdom sets her table, and Lady Folly sets hers. The whole point of the contrast is to set before the reader a choice, an alternative. Either you go this way, or you go that way. The prophet Elijah on Mt. Carmel speaks the same way—if YHWH is God, serve Him. If Baal is God, serve him. But do not dither in between.
So you are invited here to sit down and taste the bread and wine that the eternal wisdom of God set for you. What He has promised, He has provided. Wisdom in Proverbs sets the table, and tells us exactly what is there (Prov. 9:2). Folly is a bit more vague, promising only that stolen water and bread eaten in secret will be “delicious” (Prov. 9:17).
Wisdom promises a true banquet, and what she promises is likely in the background when Jesus describes His great feast (Luke 14:16-24). This bread that you can chew is what wisdom tastes like. This red wine gives you the chance to taste, savor and swallow wisdom.
But these are invitations and promises, and the only way to receive them is to believe them. So come, now, to Jesus Christ, and welcome.
