Here are some examples of what I'm talking about...(taken from Making Brothers and Sisters Best Friends)
Everything belongs to the Lord (Ps. 24:1)
Anything we have, including our own bodies, belongs to God. (I Cor. 6:20)
We are only stewards of the things God has given us. (Mt. 25:20-21)
It is God's responsibility to protect His own property. (Rom. 12:19)
We have no rights at all. (Gal. 2:20)
Rather than standing up for our wants, we must die to ourselves. (Jn 12:24-25)
When we remember that each day is a gift and that everything belongs to God then we will be less likely to get upset when things don't go the way we want. We can be compassionate to our children when they are upset about something at night (that seems petty to us) instead of mad that we have to keep repeating ourselves and having our time or rest interrupted. We don't get upset in the morning when we are awaken early because one of our little ones wakes up earlier than we would like. We don't get upset when something of ours is broken or spills happen, or toilets are played in (that never happens in my house *wink,wink*), or school work is not being completed in a timely manner. Our homes can be peaceful and it can be ushered in by us, the mother's who are striving for this in the first place. And we don't have to beat ourselves up when we mess up and fuss at our children when we meant to handle things with more patience and compassion than we did. We just ask our children to forgive us and try harder next time. And in the process we are teaching our children to do the same.
So, be encouraged. You're not alone. Recognize what is really upsetting you and then realize it's not yours anyway, then you will be less likely to get upset, and there will be more peace in your home.
