Immediately after finding his true faith, Lewis spared no time in producing prose works that explained and defended his belief. He dedicated himself to writing for the millions around the world who were struggling with their Christian faith and were asking questions. His suffering and doubt allowed him to empathize with those who had a hard time accepting God. His main goal was to provide an answer for those who thought an answer did not exist.
Not only did he write for adults like him, he wrote children's books as well to make sure he was able to get across to everyone. C. S. Lewis used his talented mind with the great knowledge he had in order to help millions around the world instead of keeping his knowledge to himself. The sacrifice of time, effort, and money he took into making these books shows how dedicated he was to helping people he had never met before out of the kindness and mercy of his heart.
Despite having a higher education than most and gaining money from his works, Lewis never become proud or arrogant. He simply did what he could to help others with what he had.
With the money he gained, Lewis used it to support impoverished families and to pay for the education fees for orphans, as well as putting money into multiple charities and church ministries. This aspect of C. S. Lewis is what separates him from most successful writers and literary critics.
