Isaiah 62

It only took me about 2 minutes to read this chapter. There were two thoughts in this chapter that caught my attention. Verses 4 and 5 when God speaks of his marriage to his people of faith. And the next two verses when he speaks about the watchmen. Why does God want us to remind him of his promises? We know that he can choose to forget our sins, but can he choose to forget his promises? I don' think so. So what is the purpose of the watchmen? Maybe the watchmen are a representation of all the people; called to prayer. I think that God wants us to speak his promises so that in giving those promises a voice we'll be more likely to remember what he had promised to us. And that City of Peace; isn't that the completed picture of the church world-wide?
