Haggai 2: 20-22
God works on His timeline, not ours. Zerubbabel received a special word from God through Haggai that encouraged him to be faithful to God and see what would happen. When we are in the middle of a difficult situation it is important for us to wait and have faith that God will act on our behalf.
It had been 15 years since they had returned to Jerusalem and rebuilt the wall under Nehemiah's leadership. They were suffering because they had not followed God's instruction to also rebuild the temple. Much like our current situation in the world today, they were too concerned with pleasing themselves and those around them instead of putting their faith where it belongs... in God who had seen them through so many other trials.
