God's recovery program for fallen mankind is always sanctification.
Christ's New Testament church was born into a sin-warped, dark-hearted world of mixed-up marriages, sin-scarred lives, and confused families.
As we open to the book of Titus never forget that is the context. Paul, guided by the Spirit of God, was writing a letter to Titus, the missionary church planter sent to the island of Crete.
Roman culture in the First Century was closed to God's ways. That meant that every man and woman on Crete had been born into a sin-warped society. Each person Titus encountered was living out their life each day darkened by sin, enduring mixed-up and struggling marriages, and limping along with sin-scarred lives and families. But despite their failures, God wanted to make them useful again.
God knew that the men and women who were gloriously saved could not automatically become great wives and mothers, or husbands and fathers. When they came to Christ and were forgiven, God graciously gave them everything they needed to become godly wives, mothers, husbands, and fathers. But, they needed something else called sanctification to change them into useful servants of God.
The book of Titus captures the pattern God gave for every believer as the goal and direction of their life. Being a Titus 2 person of godliness should be the desire of every parent for their child; and every partner for their mate; and of every believer for their own life.
