2 Thes. 2:13: But we ought always to thank God for you, brothers loved by the Lord, because from the beginning God chose you to be saved through the sanctifying work of the Spirit and through belief in the truth (NIV).
We do not always know how faithful we are until we are tested. Trials have a way of exposing those areas where we are trusting in ourselves instead of relying on God. Paul encouraged these believers by showing them the value of God's sanctifying work in their lives.
The purpose in sanctification isn't to reveal a person's heart to God. He already knows! Rather, it is to reveal the heart to the person himself. This can be painful at times as we are confronted with the depths of our sin and challenged to mature spiritually
Pray for God to expose the "logs" in your eyes and the strength to embrace the sanctification process. Difficult times provide an opportunity to become more Christ-like and to be a humble example for our family.
Trials expose our weaknesses and challenge us to grow spiritually.
