You would think this the crowning argument. The temple of God in Jerusalem.
You and I as believers are individually temples, and together in a church, we are collectively a temple. ‘As God hath said, I will dwell in them, and walk in them.’ We have a holy of holies within us, and God is resident by the Holy Spirit. ‘And I will be their God, and they shall be my people.’ How can you share and bring an idol in? And churches mix with false teachers or accept them? Or in courtship, enter into marriage and allow an idol into your heart?
