How Long Should a Widow Mourn?

How Long Should a Widow Mourn?
Proverbs 31:12 KJV She will do him good and not evil all the days of her life.

Scripture teaches it is better to go to the house of mourning, than to go to the house of feasting, and, sorrow is better than laughter.

Ecclesiastes 7:1 KJV A GOOD name is better than precious ointment; and the day of death than the day of one’s birth. 2 It is better to go to the house of mourning, than to go to the house of feasting: for that is the end of all men; and the living will lay it to his heart.
3 Sorrow is better than laughter: for by the sadness of the countenance the heart is made better.
4 The heart of the wise is in the house of mourning; but the heart of fools is in the house of mirth.

A widow many never find "closure" until the day God wipes her tears off her face in Revelation 21:4.

Revelation of John 21:4 And God shall wipe away all tears from their eyes; and there shall be no more death, neither sorrow, nor crying, neither shall there be any more pain: for the former things are passed away.

Either a widow mourns for her husband until the day she dies, or she gets remarried and can continue bearing children and keeping house.

I Timothy 5:11 But the younger widows refuse: for when they have begun to wax wanton against Christ, they will marry;
I Timothy 5:14 I will therefore that the younger women marry, bear children, guide the house, give none occasion to the adversary to speak reproachfully.

The scriptures say a widow is happier if she continues mourning but that a widow has liberty to remarry, in the Lord (I Corinthians 7:8-9, 39-40).

I Corinthians 7:8 KJV I say therefore to the unmarried and widows, It is good for them if they abide even as I. 9 But if they cannot contain, let them marry: for it is better to marry than to burn.
I Corinthians 7:39 KJV The wife is bound by the law as long as her husband liveth; but if her husband be dead, she is at liberty to be married to whom she will; only in the Lord. 40 But she is happier if she so abide, after my judgment: and I think also that I have the Spirit of God.
