Do not speak harshly to an older man, but speak to him as to a father, to younger men as brothers, to older women as mothers, to younger women as sisters—with absolute purity. Honor widows who are really widows. If a widow has children or grandchildren, they should first learn their religious duty to their own family and make some repayment to their parents; for this is pleasing in God’s sight. The real widow, left alone, has set her hope on God and continues in supplications and prayers night and day; but the widow who lives for pleasure is dead even while she lives. Give these commands as well, so that they may be above reproach. And whoever does not provide for relatives, and especially for family members, has denied the faith and is worse than an unbeliever. (1 Timothy 5:1-8, NRSV)
Who needs to care for others?
We all do. We need to make sure that our family is taken care of.
That they have all they need, and that they do not have to live alone.
We are called and equipped to care for the other, and if the other has no family, they become our family.
We are called to love as God loved us.
