Proverbs 27:17 ((NIV)
"As iron sharpens iron, so one person sharpens another."
"Iron cutting tools are made bright, and sharp, and fit for use by rubbing them against the file, or some other iron. So a man, who being alone is sad, and dull, and inactive. The company and conversation of a friend refreshes him. His very wits are sharpened and his spirit is revived."
There is mutual benefit in the rubbing of two iron blades together; the edges become sharper, making the knives more efficient in their task to cut and slice. In the same way, we as a friend, as God peculiar people, as a brother, a sister, son, daughter, mother, uncle, father etc sharpens one another. Believe me, we were made for each other! We must seek the betterment for each other. We all need a helping hand at some point in our lives. Someone to show us the way, someone to confide in.
