The increasing collapse of the family unit in our society means there will be an increase in the number of widows that need to be under the church's care. For instance, a Christian widow with several children might not receive any help from unsaved parents. The church needs to discern which widows are in genuine need of financial care. It cannot indiscriminately give to everyone. So Scripture lays down some guidelines to determine who qualifies and who doesn't.
Many widows have children and grandchildren.
Family members are the first ones responsible to care for widows. The first place for children and grandchildren to demonstrate their godliness is in the context of family living, which includes making sure each family member is provided for. Relating well to each other is an indication of a godly family. Perhaps even an application of enrollment for a seminary student could include a letter of reference from the parents. Children are to give back a return to their parents, which includes a financial obligation.
