If you have been chosen, saved, and justified by God, you are and will be sanctified by God. If you are not being sanctified, then you have never been justified. Sanctification is indeed a good and helpful testimony to the genuineness of salvation. Its presence testifies to genuine salvation. Its absence testifies to the lack of salvation. Sanctification and growing in the likeness of Christ is a testimony to the power of God working in the life of those God has saved.

Is your life worthy of imitation? If new believers imitated your walk with God, would it be to their benefit? If fellow members of the church imitated your holiness, would they walk in righteousness? If the younger members imitated your worship attendance practices, would they be pleasing to God? The answer to these questions for Christians must be "Yes."
