Now before the Feast of the Passover, when Jesus knew that His hour had come that He should depart from this world to the Father, having loved His own who were in the world, He loved them to the end.
2 And [a]supper being ended, the devil having already put it into the heart of Judas Iscariot, Simon’s son, to betray Him, 3 Jesus, knowing that the Father had given all things into His hands, and that He had come from God and was going to God, 4 rose from supper and laid aside His garments, took a towel and girded Himself.
John 13:1-4, NKJV
You cannot have service for God until supper has ended. It is significant to note in the text, that Jesus did not gird himself with the towel until supper ended. The feeding phase was followed by service. God fuels those who will burn off the fuel in service. He feeds those who serve. He says, “I give seed to the sower.”
If you feel you are not being fed, maybe it is because you refuse to serve.
