For many years I went to church faithfully, week after week, but I wasn't living a victorious Christian life. I read my Bible every day, served on the evangelism board and went door-to-door telling people about Jesus because I really wanted to serve God. But even though I was doing those things, I was still miserable most of the time.
See, I learned a good foundation about salvation through God's grace at my church, but I wasn't learning how to change and be transformed into the image of Christ by renewing my mind according to God's Word. So I would go to church on Sunday, fight with my husband during the week, get frustrated with my kids a lot, and feel miserable, depressed, angry – like a mess – and then go back to church on Sunday. I felt like I didn't know how act like a "sane" human being.
Ephesians 4:23-24 (AMP) says to "be constantly renewed in the spirit of your mind [having a fresh mental and spiritual attitude], and put on the new nature…created in God's image…."
This is so important, because it's impossible to have a positive, peaceful life and at the same time have a negative mind.
