Anyone who plans on dragging their genealogy charts before the Lord at the end as something to insure their salvation is quite likely to be found lacking a proper wedding garment. I somehow don't think the Lord cares to whom we are kin by flesh & blood, just whether Jesus Christ the Son of God is our brother by virtue of us being washed in His blood & us being adopted by the Father in Heaven. There is truly neither Jew nor Greek, male nor female in Christ as Scripture plainly tells us. - I don't know exactly how the Lord is going to deal with every single little detail at that last trump, but it is surely not something dependent upon me being able to figure out. He managed Creation without my input.
Hello???!
OF COURSE
Geneology charts have nothing to do with Salvation given the New Covenant.
But the point is irrelevant.
Has nothing to do AT THIS POINT, POST CROSS AND RESURRECTION, WITH
GOD'S PROMISE TO HIS BUDDY ABRAHAM.
