The work of the temple, as we already know was discouraging. Most of Zechariah’s prophecy was to encourage the people and little could have encouraged them more than these words. “You are not going to do this work in your own strength or your own power,” God told them, “you are going to do the work by My Spirit!”
When we try to serve the Lord today we are going to go through some tough spells. It is not always going to be a mountain top experience. Often when it gets like that we can try to do things our own way. We get desperate and we try to figure out what more we can do. We can even begin to see ourselves as failures.
God’s reminder is for all of us. We are not going to succeed on our own. God is going to do His work through us in His way if We are in fellowship and obedience to Him.. This does not take away our responsibility to be faithful in service and obedience, but it does help us with the pressure to succeed.
