I will give you a new heart and place a new spirit within you. I will remove from your body a heart of stone and give you a heart of flesh in its place.
If you, then, despite your evil nature, know how to give good gifts to your children, how much more will the heavenly Father give the Holy Spirit to those who ask him!
But whoever drinks the water that I will give him will never be thirsty. The water that I will give him will become a spring of water within him welling up to eternal life.
Therefore, you will be given this sign by the Lord himself: The virgin will be with child, and she will give birth to a son, and she will name him Immanuel.
Do not worry about anything, but present your needs to God in prayer and petition, with thanksgiving. Then the peace of God, which is beyond all understanding, will guard your hearts and your minds in Christ Jesus.
