Whatever you do, work heartily, as for the Lord and not for men.
Colossians 3:23

2 “Thus says the Lord of hosts: These people say the time has not yet come to rebuild the house of the Lord.” 3 Then the word of the Lord came by the hand of Haggai the prophet, 4 “Is it a time for you yourselves to dwell in your paneled houses, while this house lies in ruins? 5 Now, therefore, thus says the Lord of hosts: Consider your ways.
Haggai 1:2-4

Delayed obedience is disobedience.

1 Now the prophets, Haggai and Zechariah the son of Iddo, prophesied to the Jews who were in Judah and Jerusalem, in the name of the God of Israel who was over them…
5 But the eye of their God was on the elders of the Jews, and they did not stop them until the report should reach Darius and then an answer be returned by letter concerning it.
Ezra 5:1,5

1. The Lord sees all.

And this was their reply to us: ‘We are the servants of the God of heaven and earth, and we are rebuilding the house that was built many years ago, which a great king of Israel built and finished.
Ezra 5:11

2. Be servants of the Lord.
