Matthew 1:24-25 (Taken from the NKJV)
24 Then Joseph, being aroused from sleep, did as the angel of the Lord commanded him and took to him his wife, 25 and did not know her till she had brought forth her firstborn Son. And he called His name JESUS.
I came upon this verse and had some problems digesting it. Would anybody be kind enough to explain it to me, with the most emphasis on verse 25?
