4) He is there at the right hand of God to pour out the Holy Spirit upon us.
This is one of the first things that Peter said about what Jesus' ministry now is after He has ascended. This is in Acts 2:33. He says, "Therefore being exalted to the right hand of God, and having received from the Father the promise of the Holy Spirit, He poured out this which you now see and hear." Remember these people who are listening to his sermon had seen the tongues of fire and the rushing mighty wind and visibly the Holy Spirit had come upon them, and audibly. And so he is saying "There it is!" Proof that He is sitting at the right hand of God doing His job. He is pouring out the Holy Spirit upon His people.
