Salvation is the good work God begins in you by the infilling of the Holy Ghost. Now you must continue to work out your salvation through sanctification and service until Jesus Christ returns.
God’s purpose for his Saints is to go through challenging situations is to refine and purify our character, making our faith stronger and resolve more resilient. It’s an opportunity for spiritual growth (inward transformation), as we emerge from our fiery trial with a renewed sense of purpose and a deeper commitment to serve and please God.
