Walking in wisdom is doing our work,

. . . paying our bills, and keeping our promises. 

Colossians 4:5 Walk in wisdom toward them that are without, redeeming the time.

"Walking in wisdom" also means that we are careful not to say or do anything that would make it difficult to share the Gospel. It means we must be alert to use the opportunities God gives us for witnessing. "Them that are without" are the unsaved, and they need Jesus.

"Redeeming the time" is what women do when they find a bargain. They buy it. Wise Christians seize opportunities to win souls to Christ. 

With grace in our hearts and on our lips, we will be faithful witnesses and not judges or prosecuting attorneys.
