When the angels had gone away from them into heaven, the shepherds began saying to one another, “Let us go straight to Bethlehem then, and see this thing that has happened which the Lord has made known to us.” So they came in a hurry and found their way to Mary and Joseph, and the baby as He lay in the manger. When they had seen this, they made known the statement which had been told them about this Child. And all who heard it wondered at the things which were told them by the shepherds. But Mary treasured all these things, pondering them in her heart. The shepherds went back, glorifying and praising God for all that they had heard and seen, just as had been told them. Luke 2:15–20, NASB
Human faith is not the same thing as Genuine (saving) faith. The former is based in Human reason and intellect. The latter is supernatural. What passes for faith in many professing believer’s “Christianity” is a belief based in who preaches to or teaches them. This is not Genuine faith because it is not a belief in the Word or in God through the Word. These are “believers” who will eventually fall away. Some may last a lifetime, but if the fires of tribulation come upon them they slide into apostasy because their faith is not of the substance that endures.
