“But he said to me, “My grace is sufficient for you, for my power is made perfect in weakness.” Therefore I will boast all the more gladly about my weaknesses, so that Christ’s power may rest on me.” 2 Cor 12:9
Paul pleaded with God to remove a thorn in the flesh, but God told him, “My grace is sufficient for you”. It kept him from being proud and from boasting about himself. Grace is efficient where human possibility is inadequate.
My encouragement to you: don’t let your challenges keep you from trusting God. He has a destiny for your life. He can and will use you for His glory in any condition. God has made available to all believers the provision of unending grace.
