That was the lesson of Cornelius, the commission of Paul, the rebuke of the Scribes and Pharisees - and the operative part of this excerpt from John's Gospel (emphasis mine):
I agree.
However, it would have been a blessing to hear that any unbroken lineage of people had remained SPIRITUALLY faithful to the Lord.
Unfortunately, they did not.
You can’t help but wonder, though....it would be a blessing for me some future day to look down from my place in that “great cloud of witnesses” who’ve crossed to the other side to see that my descendants had remained true to the faith of their fathers.
