What a fine example of the fulfilled marriage vow, "Until death do us part." Ate Delia made a commitment before God and Christ and His Church over 40 years ago to Christopher Foxworth and then kept that commitment all of the way to the end, the end of her natural life. Her example in marriage shines as an understanding of what it means to be "faithful unto death" to our Savior, as well - we make a commitment to Jesus Christ to be faithful unto death and we keep that commitment.
Rev 2:10b-11
Be faithful until death, and I will give you the crown of life. He who has an ear, let him hear what the Spirit says to the churches. He who overcomes shall not be hurt by the second death.
