Luke 24 - The promise of the Father is the promise that His Spirit would dwell in His people. 2017

Luke 24:49
"And behold, I am sending forth the promise of My Father upon you; but you are to stay in the city until you are clothed with power from on high."

The promise of the Father is the promise that His Spirit would dwell in His people. It is not a separate entity, but the breath of the Father.
