How can Christians find joy in their struggles with sin?

In 2 Corinthians 12:9, we learn that God's power is made perfect in our weakness. This means that struggles with sin can be avenues of grace where believers are reminded of their dependence on God. As we acknowledge our failures and weaknesses, we turn to God for strength and forgiveness, which fosters a deeper relationship with Him. Joy arises not from the absence of trials, but from the assurance that God uses our struggles to teach us reliance and humility, ultimately drawing us closer to Him and enabling us to experience His sustaining grace in our lives.
