Yes I have addressed it but you are not listening.
Your problem is that you think that there was only one promise concerning the Spirit and that is false, for Jesus in John 14-16 and especially chapter 16 promised the indwelling of the Spirit and that began to be fulfilled when he breathed on the disciples but right before left to sit at God's right hand, he promised the Baptism of fire and the Spirit and this is not the same promise.
By the way, Jesus didn't mention a Baptism of the Holy Spirit in John 14-16 but only that the Holy Spirit would be with them and dwelling within them and the same goes for Acts 1:4-8, for here Jesus didn't mention the indwelling of the Spirit at all but only the Baptism of the Spirit instead.
Therefore can you respond to the difference between the indwelling of the Spirit and the Baptism of the Spirit?
The word Baptism doesn't mean an indwelling of the Spirit but rather being totally immersed in the Spirit, so how do you respond to that?
As far as him having to go away first, that applies to both promises and so that doesn't help your argument on this at all.
Tell me, are you a United Pentecostal believer?
For that would explain why you are having problems with this.
