The book or Mark’s account of Christ’s early ministry is pretty important, because it tells us who Jesus appointed to continue his work here on earth. The miracles that were recorded, are also important. Because the people who were healed, were healed because they believed in Jesus Christ and the healing’s also could teach us some really important lessons. One of those lessons is that all things are possible if we believe in God and Jesus Christ (and the Holy Ghost). Another lesson that Christ taught was that he came here on earth to redeem the ones who needed to repent and not those who were already righteous. If we are looking for a role model of who we would like to become like, then Jesus Christ is a great example. Jesus was kind but firm, a master but served, pure (sinless) but took our sins upon him, saved many (us) who do/did not deserve to be saved, innocent but accused of breaking every (or almost) single law, and many other things. He came here on earth to show us the way to have eternal life.
Jesus Christ taught in parables, and all which both applied back then and applies in now a days. He did his teachings in a way that we could understand them, by applying the Kingdom of Heaven to everyday things (food, containers, ways of a sower, etc…). Jesus Christ did some impossible things that we cannot do without help of some kind (Ex: walking on water, dividing 5 loaves and 2 fished among 5000 men with lots to spare, etc…).
How important were the miracles in the book’s account of Jesus’ early ministry? To summarize it up: the miracles in the book’s account of Jesus’ early ministry were important because it showed us that with God, NOTHING is impossible, and Jesus also showed us the way how we should treat people, and many things like that. And many other things.
