may you have peace.
Your sister is correct: by means of faith, some have... and will... save their entire households, excluding those who simply refuse to heed whatever minor instructions may go along with such salvation. I give you:
Noah (his faith resulted in salvation not only to his wife and sons, but the wives of his sons, as well)
Lot (his faith saved both daughters; could have saved sons-in-laws, but they wouldn't go, and could have saved wife, but she failed to heed to warning against looking back)
Moses (his faith saved millions of Israelites as well as Egyptians; unfortunately, their contention due to a lack of faith resulted in the loss of many of their lives)
Rahab (her faith saved all those in her household who followed the instructions, including in-laws, etc.)
Cornelius (by means of his faith, all of his household and other sundry relatives, received the blessing of holy spirit)
It has always been this way: a man's faith can "atone" for his household... with the exception of those who deliberately disobey an instruction that could mean life... or those who willingly deny such salvation.
That is why it is upon us ALL... to seek God's favor... not by works of the Law, but by works of faith, because by doing so, we can save not only ourselves, but our households.
This has been one of the "themes" since Adam: Adam was entrusted with the safety of ALL of earthling man... but for his own desire... he delivered up ALL of earthling man, rather than gave his life to keep them safe. In contrast, the Christ... gave HIS own life... to save all of ours. He fulfilled the Law so as to RELEASE us all from the "wage" which Adam brought upon us. We, then, are OBLIGATED... if not for our fellowman, then for our loved ones... to try and seek God's mercy... on our own behalf and their. Through Christ... this can be done.
Thus, the "work" I do is for the sake of:
1. My love of God, for I now know Him to actually BE love, contrary of what the writings of the Jews and others may portray;
2. My love of His Christ, for by means of him and his life and teachings, I have come to know how God truly is, for he bore witness TO that truth in what he did, didn't do, said and taught;
3. My love of my children and family, that perhaps by my faith, they will be shown mercy;
4. My love of my "neighbor"... including all of you here... for whom I pray and seek mercy constantly, whether you desire it or not, because I do not do it because you all ask for it... but because I "want" to - I understand you because I was "there" once before, too; and
5. My love of self, in that God has called me through His Son... and because they consider me worthy to bear the "torture stake" of my Lord so as to grant me to suffer for HIS sake by going to all that he sends me and sharing with them what he directs me to... even in the face of much ridicule and persecution... almost unbearable at times... I know that I am doing a work that, while heavy and fearful now... may save my children... and myself... but just having the privilege of being a "good-for-nothing-slave" during this time... is quite exciting... and so is enough...
Many of us... like Adam... have "learned" to think only of ourselves. We are not concerned for any others, particularly our children, so that our "worship" is actually quite self-serving. But the man Job was different: he knew he had little or no control over what his children did or thought or didn't do or think. Yet, he showed his love for them, one, by not giving up HIS integrity, and two, by taking on the RESPONSIBILITY of acting as "priest" on behalf of his entire household, thus making supplications not for himself only, but for his children as well:
"And it would occur that when the banquet days and gone round the circuit, Job would send and sanctify THEM; and he got up early in the morning and offer up burnt sacrifices according to the number of ALL of them; for, said Job, 'MAYBE my sons have sinned and have cursed God in their heart.' THat is the way Job would do always."
So Job did not limit he pleas to God for his own benefit - he also remembered to seek mercy for his children as well. And so did Rahab, her children and her entire household. Noah, Abraham, Lot, Cornelius... all did so.
And we can and should do so, too. For God HEARS the prayers of the "righteous"... and the "righteous" are NOT those who are perfect... but those... who EXERCISE FAITH.
I bid you peace.
