It is a daily activity to work on one's character. My tools are the Bible and Science and Health with Key to the Scriptures. I don't really know where I began, but when I saw I needed to be serious, I was told to begin with the Ten Commandments.
Study to show thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth. II Tim. 2:15
And that ye study to be quiet, and to do your own business, and to work with your own hands, as we commanded you; I Thessalonians 4:11
How does one study the Bible? It's not just a matter of reading it. It is looking up the meaning of words in a dictionary; reading what others have written; reading different versions of the Bible. Pondering, reflecting on the meanings and how it applies to your issue. Being inspired.
