Today is Ascension Day on the church calendar, celebrated 40 days after Resurrection Sunday. It is one of the most important and rich church celebrations, yet it is also one of the most overlooked. For an explanation of some of the richness of Ascension Day, Doug Wilson’s Ascension Day sermon is worth reading, after a brief snippet:
Our union with Christ, effected through the instrument of living faith alone, is a union well represented by our prefix co. Greek has a similar prefix representing the same reality, which for them is sun. As Paul put it, we were co-quickened in Christ (Eph. 2:5), and co-raised with Him (Eph. 2:6). We were also co-seated with Him in the heavenly places (Eph.2:6), and this means that today we are celebrating the exaltation of the new mankind in Christ—for it was on this day that we co-ascended in and with Him into the throne room of the Ancient of Days.
This is not esoteric theology; this is why our prayers are heard. This is why we are able to pray in Jesus’ name. This is why our souls have a heavenly security, beyond the reach of anything that stings or harms.
