Holiness
Everything we experience is an opportunity to grow in our holiness. God can “make us worthy and powerfully bring to fulfillment every good purpose” by giving us circumstances that cause us to depend on Him, to trust in Him, and to respond according to His will.
In other words, through our circumstances we allow God to mold us into a loving, forgiving, humble person versus a bitter, frustrated, angry person. (2 Thessalonians 2:11-12)
