As Jesus walked with a crowd pressing about Him, a certain woman with a hemorrhage sought to touch Him, knowing that if she could only do that, the touch would heal her, but she was not expecting the Lord to notice,

And Jesus, immediately knowing in Himself that power had gone out of Him, turned around in the crowd and said,

“Who touched My clothes?” (Mark 5:30).

He knew that she had touched Him, and not just His body, but His clothing, although she tried hard to be discreet, perhaps hoping that the crowd around Him would prevent Him from knowing what she had done.
Does the Lord know what you do for Him? Yes, He knows in every way that you seek to contact Him, and to be like Him. Do not give up!
