Charles Ellicott Commentary 2 Corinthians 13:3

"seeing that ye seek a proof of Christ that speaketh in me; who to you-ward is not weak, but is powerful in you:" — 2 Corinthians 13:3 (ASV)

Which to you-ward is not weak.—There is still a touch of indignant sadness in the tone in which the words are uttered. Men will not be able to cast that reproach of weakness upon Him whose might they will feel all too keenly.
