Why is it important for Christians to submit to God's will in sickness?

Submission to God's will when facing sickness allows Christians to engage in an act of faith, recognizing His sovereignty and wisdom. This aligns them with the understanding that their suffering has a purpose and can be used for their good and God's glory. For example, they can learn patience and grow in empathy for others who suffer (Galatians 6:2). Trusting in God's plan, even in affliction, ultimately leads to spiritual growth and a deeper reliance on Christ, who holds all things together.
