Highway Media has a series of four advent videos that you could use as a creative way to highlight advent at your Christmas services this year.
You can see the full package at Worship House Media.
In personal experience we did use these one year and they went fairly well. They are a bit more abstract and the themes aren’t as overt as some advent videos. This can be good for some, but for others they may find it hard to make connections to the theme. Either way it’s worth considering and a bonus to have 4 videos for advent in one package.
