"Therefore the Lord himself will give you a sign: The virgin will be with child and will give birth to a son, and will call him Immanuel."
The name Immanuel means "God with us." This is to show that the child Jesus is a part of God. He is with everyone at all times. Even way back in the beginning of the Bible it says in Deuteronomy 31:8 "The LORD himself goes before you and will be with you; He will never leave you nor forsake you. Do not be afraid; do not be discouraged."
I don't know about you but this scripture encourages me so much in times when I do feel afraid and discouraged about a situation. Say it and claim it over and over in your life and I promise the strength you need will be supplied. Our God is so worthy to be praised just knowing that He promises in his word that He will never leave us. The almighty is so great, Hold on because the day is near!
