"And the foreigners who join themselves to the LORD, to minister to him, to love the name of the LORD …these I will bring to my holy mountain and make them joyful in my house of prayer …” (v6-7). God’s plan, according to Isaiah, was to redeem both the “outcasts of Israel” (v8) and all those who called on Him. He promised to honor and bless even those rejected by Law and society, like eunuchs (v8). Therefore, “Keep justice, and do righteousness, for soon my salvation will come” (v1).
“For my house shall be called a house of prayer for all peoples" (v7). Jesus calls us to be His house, a new community, a bright light pointing toward His coming kingdom.
