Almost every page of my mother's Bible has verses underlined in red, and many pages have a note in the margin. She not only read the Bible she lived it. It was her guidebook.
When she passed away, she noted that she wanted me to have her Bible. I Timothy 6:6-7 was bookmarked. "But godliness with contentment is great gain. For we brought nothing into this world, and it is certain we can carry nothing out."
This was her guide for living. Now, she is living in riches beyond imagination.
