“…but he said to me, ‘My grace is sufficient for you, for my power is made perfect in weakness.’ I will all the more gladly boast of my weaknesses, that the power of Christ may rest upon me. (2 Corinthians 12.9 – RSV)
“MY grace is sufficient for you.”
I am bold enough to read that as “The grace which is ME living in you and expressing MYSELF through you, is sufficient for you.”
My sufficiency is participating with others in the “shared-life” of Christ Jesus. In so much as I do so (live out baptism by unceasing repentance) I actually share the life of Christ Jesus and HIS life is manifest through me; AND I actually realize and live into the shared-life with others that is ours in Christ Jesus.
“My Lord IS my life,” AND “My brother (and sister) IS my life.”
So, we share in life and life is shared through us.
“You must look at your own conscience and judge yourself. This is your duty, and your most beneficial pursuit. This is your duty – but is it easily carried out? Will you ever reach the point of correctly judging yourself? Study a bit, and you will find out that, in the face of a multitude of cares about your own sins, you will find no time to take up the sins of others. Study a bit, and you will learn that a great deal of attention, labor, self-compulsion, and time are needed to discern the sins of your emotions, your imaginings, your thoughts, your desires, your intentions, your tongue, your sight and hearing, and your sense of touch. Go, study a bit more, and you will learn that if you know your own weaknesses and faults well, you will not be able to bring yourself to cast a severe sentence upon the deeds of others.” – St. Philaret of Chernigov
