The purifying work of the Holy Spirit commences in the believer when he first turns to Christ. Sometimes the Spirit works on us in the fire of adversity, through which the Lord promises to take us for His good purposes (Isa. 43:1–7). When we face trials in our lives we have an opportunity to prove our faith and reliance on God. If you face trouble this day, consider how the Lord may be using it to purify your soul.
