Is Jesus presently seated on a throne?

We often say or sing that Jesus is currently enthroned in heaven or seated on His throne in heaven. However, does Jesus instead teach that He won't sit on His throne before the Second Coming (Matt. 19:28; 25:31; Luke 1:32)? Furthermore, don't the Scriptures teach that at present, rather than being on the throne, Jesus is "seated at **the right hand of the throne** of the Majesty in the heavens" (Heb. 8:1, NKJV, emphasis mine; cf. 12:2)? It seems as if He isn't seated on the throne even now but is rather seated *next to* the throne. Am I missing something? It does seem familiar to me that a verse exists describing Jesus as presently on a throne, but I can't recall where in the Bible, if anywhere, such is said. Do the Scriptures teach that Jesus is on His throne now, or is that only a future event? **Note:** I am not looking for "Jesus is outside time anyway" answers, as this type of response distracts from the real issue. Regardless of whether Jesus may perform some acts outside of time, there are clearly events He's done within time, such as coming to the earth. Likewise, Christ's being seated at God's right hand also appears to be an event in time, for example, taking place after His ascension.
