@seawulf575 explained it well. I will add that every ”Bible believing Christian” church teaches these concepts to its members. If you find one that doesn’t, that’s what we call “culturally Christian” (yes, we really do use those terms).
As for myself, at one point in my life, we had 10 people and 4 generations in our house. There was a kitchen schedule, a shower schedule, and a laundry schedule. There was a basket of keys by the front door so we could change out the cars in the driveway. The house was often messy and noisy. It was nuts.
In addition, everyone in my life seemed to be angry, and I was often the recipient of that anger. I remember one morning my husband tried to start an argument with me before I even woke up!
Instead of being upset, I was so filled with joy that I managed to keep a straight face until I left the bedroom, then chuckled all the way down the hall to the kitchen. I made a wonderful breakfast for the family and had a great day.
It was a most unusual experience, but I lived like that for two years, and I will add that for me, it was actually fun. I looked forward to every day with anticipation, peace and joy- what would God do next?
The firey darts of the enemy (the arguments and the grumpy comments directed at me), never reached me because I was using all the spiritual armor mentioned in Ephesians chapter 6.
That was 23 years ago. I often remind myself of that time, because that is still my goal today. I have found freedom in ways I never dreamed possible. I have walked in peace so long, that everything feels wrong if I don’t have that peace, and I am scrambling to get back to it.
