Paul’s letter to Titus urged him to remind Cretan believers that while they live in a sinful culture, they can be transformed into a new humanity by the same grace that Jesus demonstrated when he died to redeem them.
As a new humanity, they can reject a lifestyle that is inconsistent with God's generous love. They can show God's salvation message and transform their communities by participating in Cretan culture, rejecting anything corrupt, living and devoting themselves to Jesus, and promoting the common good.
