There is no mistaking this, that the Day of Pentecost was a day of revelation, of marvelous illumination. The very first effect of the Holy Spirit's coming at Pentecost was to change all their sense of disorder or un-order and chaos, into a mighty sense of purpose and plan. They're now an integrated people. They are not only gathered in one upper room, they are gathered now under one mighty Spirit making them inwardly a unit. And what is it that does it? By the Spirit they have become possessed of this consciousness: 'We are in a mighty movement God, in a mighty going of God, in a mighty plan of God. There's meaning in life; there's meaning in things.' You don't get anywhere until you have this sense, this strong sense, that you are called according to purpose. And you never have that sense until the Holy Spirit comes in. And the Holy Spirit never comes in until Jesus is Lord.
