"... Knowledge puffs up, but love edifies." - I Corinthians 8:1 (NKJV)
To edify is to build something from the ground up ... like people ... toward the direction of their purposes and dreams.
We can know much and build little.
Knowledge plus pride is just puffiness.
Knowledge plus love brings wisdom.
Wisdom leads to good choices.
Good choices lead to growth.
Love is wiser than knowledge. It takes knowledge and humbly employs it in the service of others.
The test of love or puffy knowledge is in whether or not people are being built up.
