The world now consists of nearly 2 billion people who follow Christianity as their religion accounting for about one-third of the total population of the world. The Christianity consists of the adherents which form a huge part of the population. These results of the battle of Milvian Bridge had immense after effect which was possible only due to the presence of Cho-rho. That particular day proved the supreme power of God and the Holy Spirit. It showed what the Holy Spirit does and a real can prove was seen in this world.
This result was possible only due to the presence of the Holy Spirit. The then Constantine was to fight against a very large army than its own. The results were very clear and everyone could understand it from beforehand. If Constantine lost this battle it was most likely he and the men in his army would have to die.
