A personality that is calm is a desirable trait that may be overlooked when listing the markers of a person with good character. I bet you like to be around people who are of a calm demeanor rather than ones who are “wound up” most of the time. They probably tend to calm you down and thus help you feel better.
Children who are calmer would seem to have an increased ability to focus on the task at hand and would therefore be able to learn better. I think the ability to focus or concentrate is one of the main indicators of a smart or potentially smart child. It is good to be smart, because it increases your opportunities to serve.
Adults also need to calm down. Not only does a calm or quiet personality affect your kids/grandkids (and anyone with whom you interact), it helps you feel better and be more focused on what you need to do. Calmness increases discipline.
You might think this topic is not addressed in the Bible, but here are three scriptures from the Epistles where it is:
… But we exhort you, …, to aspire to live quietly, to mind your own affairs, and to work with your hands, as we charged you; (1 Thessalonians 4:10-11 RSV)
First of all, then, I urge that supplications, prayers, intercessions, and thanksgivings be made for all men, for kings and all who are in high positions, that we may lead a quiet and peaceable life, godly and respectful in every way. (1 Timothy 2:1-2 RSV)
Let not yours be the outward adorning with braiding of hair, decoration of gold, and wearing of fine clothing, but let it be the hidden person of the heart with the imperishable jewel of a gentle and quiet spirit, which in God’s sight is very precious. (1 Peter 3:3-4 RSV)
How calm, quiet, peaceable, and gentle are you? Do you influence others to live this way by your own life example?
O God, increase our faith
That we may take You at Your word
That we may believe it and trust it
That we may submit and follow You
And that Your Holy Name may be exalted in the process.
