Mary and Joseph were good, devout Jews, in the second half of Luke 2, we see them fulfilling all the requirements of the Old Testament Law. As they came into the temple, they were met by two elderly people, who, moved by the Holy Spirit came in at just the right time. Here we get to see, both words of prophecy about Jesus' future and how God will move, speak through and use those who make themselves available to Him. Here is encouragement, here is insight into how God works. The supporting readings are Isaiah 42 v.1 to 9 and Joel 2 v.28 to 32.
