Therefore, the Lord himself will give you a sign. Look the woman is with child and shall bear a son, and shall name him Emmanuel. Isaiah 7:14
When we look in retrospect, from the beginning of Isaiah, we find that this whole virgin birth idea was actually planned by the LORD. Few Jewish people believed this at the time, and still many do not, but when we read deeper into the Word of God, we find the clues that He had it planned this way all along. The woman gave birth to a son.
Emmanuel, God with us.
This is what the Lord promised, and this is what He gave us. Emmanuel, God with us.
Jesus, conceived by the Holy Spirit, born of the virgin Mary, came down and lay in a manger, wrapped in swaddling clothes like any other baby. As we see in His creation, He knew from the beginning of time, that Jesus was coming this way.
The Wise Men knew it. The shepherds heard about it from the angels. Mary knew it before He grew in her womb. Joseph knew it in a dream. Baby Jesus was God who came among us and lived with us for a season. His birth was joy.
