“My grace is sufficient for you, for my power is made perfect in weakness” (v9). Paul said that “visions and revelations” (v1-5) were nothing to boast about, despite their “surpassing greatness” (v7). Instead, he celebrated the fact that God revealed His kindness and power in Paul’s struggles, in “weaknesses, insults, hardships, persecutions, and calamities” (v1). When we are facing our own “thorn in the flesh” that is not easily conquered (v7), our eyes are open to how much we need the Lord’s grace every day.
“For when I am weak, then I am strong” (v10). Our own weakness teaches us to rely on the Lord, and we experience His powerful love working in us and through us.
