1 Peter 2 says believers, like living stones, are being built into what?

Answer: A spiritual house

Coming to Christ, the living stone, believers like living stones are built into a spiritual house to be a holy priesthood.

“As you come to Him, the living stone, rejected by men but chosen and precious in God’s sight, you also, like living stones, are being built into a spiritual house to be a holy priesthood, offering spiritual sacrifices acceptable to God through Jesus Christ.”— 1 Peter 2:4-5 (BSB)
