Toward them that are without (pro tou exw). A Pauline phrase for those outside the churches ( 1 Thessalonians 5:12 ; 1 Corinthians 5:12 ). It takes wise walking to win them to Christ. Redeeming the time (ton kairon exagorazomenoi). We all have the same time. Paul goes into the open market and buys it up by using it rightly. See the same metaphor in Ephesians 5:16 .
