Yes, not all widows qualify for this benevolence according to I Timothy 5.
"Let a widow be enrolled if she is not less than sixty years of age,
having been the wife of one husband,
shown hospitality,
has washed the feet of the saints,
has cared for the afflicted,
and has devoted herself to every good work.
But refuse to enroll younger widows"
Yesterday John Piper pontificated on this very issue in the Ann Landers style feature on his website:
Ask Pastor John
"Are there verses in the Bible that encourage widows to remarry? And the answer is: Yes, there are, like I Timothy 5:11-16 where
Paul wants younger widows to remarry instead of being on the special widow care ministry that existed, evidently, so that they wouldn’t be a burden on the church"
