Luke 13:25-28
Once the owner of the house gets up and closes the door, leaving you standing outside knocking on the door, [and] saying, 'Sir, [please] open [the door] for us.' and he answers you, 'I do not know you or where you came from,'
Romans 11:32
For God has made all people prisoners of a disobedient life, so that He could show mercy to everyone.
1 John 3:17
Now whoever has [a sufficient amount of] life's possessions and [then] observes one of his [Christian] brothers who does not have enough to get by on, but does not feel sorry for him [i.e., enough to help him out], surely a love for God does not continue to live in that person's heart.
