Have you thought about how brave and honorable Joseph was to take Mary as his wife. Of course, he had a little prompting from an angel of the Lord. When that angel appeared to Joseph in a dream- in a very short conversation we learn the purpose of Jesus' birth.
The angel quoted the Old Testament from Isaiah- " Behold , the virgin shall be with child and shall bear a son, and they shall call his name Immanuel," which translated means,"God with us."
Bethlehem- "God with us."
Calvary- "God for us."
Pentecost- " God in us."
Think about that today!
