Answer
In the Ascension illustration of the Rabbula Gospels,Virgin Mary symbolized the Christian Community.
Explanation
Ascension is the act of something rising or going up. This day is counted six weeks after Easter Sunday. In the ascension of Christ to Heaven, He is surrounded by four angels and below are apostles and Virgin Mary. Virgin Mary here has the status of the bearer of God and the mother of Christ. She symbolizes the whole Christian community on earth.
In life, almost all difficulties may be considered 'speed bumps' or some other similar word from reaching their own goals.
There are, in my opinion, three main types of obstacles, which are;
-Physical
-Mental/Emotional
-Outside (AKA Obstacles out of your control)
There are countless possible obstacles for each category, but to name a few for each;
-Physical difficulties may include an injury that would prevent an activity-based to be achieved or a disease that affects your inability to move towards a goal.
-Mental/Emotional goals can include disorders, diseases, or certain negative events occurring that can hinder your ability to function normally.
-Outside obstacles can be anything from weather cancelling an event you wanted to complete to a person having to opt out of something you needed them to partake in.
In conclusion, there are countless stops that resist against human goals.
