He who is slow to anger is better than the mighty,
And he who rules his spirit, than he who captures a city.
This was in my daily readings yesterday, and it really stood out to me. It is not easy to control your spirit, emotions run out of control quickly. I'm struggling, I openly admit, being pregnant and tired and trying to raise godly children sometimes seems too hard a challenge. But I must remember that God always gives us the power to do what He has commanded us too!
So, although ruling your spirit is much likely more difficult than capturing a city (it is, honest) we can do it, by putting on the new man, taking deep breaths and trying to think before we speak!
It does also make for a more pleasant life, less stress if you can keep your emotions under control - who wants to live with a woman who is always stressing? People soon have enough of that sort of unpleasantness. And children will pick it up, you will soon see them shouting first and thinking later. So I encourage you, along with myself to meditate on this verse and think before we speak/shout!
