I do notice a difference in my thinking/attitude when I spend daily time in the Bible. It has been my mainstay since my husband left though, I spent every day in it. Lately, I have let it slide. I keep verses in mind and I read verses from other things I am reading though. But it isn't the same as spending that time in the entirety of the Bible. I do have these daily devotions my church puts out that I like to do. Around Christmas my pastor told me about a special one they put out called "Where is God now?" for people that are going through difficult times. I have found comfort in the messages and also strength to continue on. There are so many other books I have read that have each helped in a certain way.
Gary Chapman "Things I wish I'd known before we got married" good for me cuz i am fairly new to marriage
Dr. Emerson Eggerichs "Love and Respect" very good for understanding what your husband or wife really desire
Jerry Bridges "Respectable Sins" very good for personal reflection
Dr. Henry Cloud and Dr. John Townsend "Boundaries" good for setting healthy boundaries with others at work or home
Donald Miller "Blue like Jazz"- more of a person walk through his faith, but brings up some very important issues surrounding faith
I also have gone through some other devotional books my church puts out. I am Lutheran.
No matter what you read, always pray for that wisdom. So that the most important parts of things touch you or lay on your heart. God will not steer you wrong.
There is one I would like to point out that I recently read. It is called "Life's healing Choices" by John Baker.
