God speaks to eunuchs and foreigners, promising both that as they keep His Sabbath “undefiled and hold fast to [His] covenant” He will “bring [them] to [His] holy hill and give them joy in [His] house of prayer.” (Isaiah 56:6) He also promises to “give them an everlasting name, a name imperishable for all time.” (Isaiah 56:5)
God promises “[His] house shall be called a house of prayers for all nations.” (Isaiah 56:7) God says, “I will yet bring home all that remain to be brought in.” (Isaiah 56:8) God does not forget or leave behind anyone who seeks Him. Rather He draws to Himself those He has chosen.
Jesus warns, “I have come to set fire to the earth, and how I wish it were already kindled! I have a baptism to undergo, and what constraint I am under until the ordeal is over! Do you suppose I came to establish peace on earth? No indeed, I have come to bring division. For from now on, five members of a family will be divided, three against two and two against three; father against son and son against father, mother against daughter and daughter against mother, mother against son’s wife and son’s wife against her mother-in-law.” (Luke 12:49-53)
Jesus comes to seek and save what is lost. He says, “I tell you, on that night there will be two men in one bed: one will be taken, the other left. There will be two women grinding corn: one will be taken, the other left.” (Luke 18:34-37)
God has chosen; He will be faithful to “bring home all that remain to be brought in.”
