consider carefully (see study note on Haggai 1:5): God gives blessing, whether spiritual or material, when his people obey him (Deuteronomy 30:6–10).
Haggai urged the people to continue examining their own actions. This careful self-examination leads to repentance (turning back to God). He also called them to continue living in the fear of the Lord (respect and obedience toward God), which his first message had already begun to produce (see Haggai 1:7, 12).
