"'From this day on, from this twenty-fourth day of the ninth month, give careful thought to the day when the foundation of the Lord's temple was laid. Give careful thought: Is there yet any seed left in the barn? Until now, the vine and the fig tree, the pomegranate and the olive tree have not borne fruit. From this day on I will bless you.'" NIV translation
The twenty-fourth day of the ninth month (in this Jewish calendar) is what we call Christmas Eve (December 24th). The prophet delivered this message to the exiles who were in Jerusalem but it is a beautiful promise to all men of the coming of Jesus Christ. God tells the people to look around them and see that there is nothing stored up from their own efforts but promises to bless them from this day forward. This is a picture of the fact that we cannot be saved by our own efforts but only through faith in Jesus Christ. We are truly blessed with a beautiful new home through Him.
"The word of the Lord came to Haggai a second time on the twenty-fourth day of the month: 'Tell Zerubbabel governor of Judah that I will shake the heavens and the earth. I will overturn royal thrones and shatter the power of the foreign kingdoms. I will overthrow chariots and their drivers; horses and their riders will fall each by the sword of his brother.'" NIV translation
The first message on this day (Christmas Eve) was a promise of Jesus coming as a baby to die for our sins.
This second message is the promise that Jesus is coming a second time to rule and reign on the earth. The prophet was to tell the leader of the people that Jesus would be coming to lead His people.
"'"On that day,'" declares the Lord Almighty, "I will take you, my servant Zerubbabel son of Shealtiel," declares the Lord, "and I will make you like my signet ring, for I have chosen you," declares the Lord Almighty."'" NIV translation
A signet ring was used to identify royalty and especially to seal royal decrees. We see that God gave His authority to Zerubbabel and this promise was extended to us through Jesus Christ. In the Great Commission (Matthew 28:18 -20), Jesus also made the disciples God's signet ring and, in Acts 2, it was extended to all believers. We are servants in this world but in our beautiful new home we will reign with God.
