What does Eve's temptation have to do with Christmas? God wants our affections directed away from false gods that make us happy for the moment to focus on Him, His love. He wants to give us a new heart this New Year.
God paid attention to every detail when He fulfill His promise to send a Savior. If He kept this big promise, know that He will keep all of His promises - to give us courage, to not let us fall, to guide us and to love us. Now and in eternity.
