For this reason the Jews were persecuting Jesus, because He was doing these things on the Sabbath. But He answered them, "My Father is working until now, and I Myself am working." - John 5:16-17 NASB
There are times when Jesus sets out an argument for healing or helping folks on the Sabbath day, but here in John 5 His answer is different, and striking.
Jesus basically tells those around Him that He is not checking His calendar to see if His actions are appropriate, He is listening to and looking at the Father.
To put it plainly, He answers them:
I know that everything you do is dictated by the calendar. You go from Sabbath to Sabbath, from Feast to Fast and back again to Feast.
But I determine the day's activities – teaching schedule and materials, healing ministry agenda, food multiplication and storm suppression – in My time with the Father.
Time with the Father, or perhaps I should say connection with the Father was Jesus’ 'ONE THING’ every day. I have ONLY come to do the will of Him who sent me.
Time for me to adopt that 'ONE THING’ as my 'ONE THING.'
How ‘bout you?
