The Holy Spirit was working in the lives of the Old Testament saints. The Holy Spirit moved him to find the Christ who God had promised to let him see before he died. God always keeps His promises. The Lord always completes His task before he dismisses His servants.
The Lord prepares and gives salvation to His people. Jesus is the light and revelation to the gentiles and the glory of God to the people of Israel. Jesus is the rising and falling of the nation of Israel. Jesus will reveal the thoughts of many hearts even His family. Anna said that Jesus is the redemption of all the people. He is the grace and wisdom of God.
