John 20.1 says that on the first day of the week, the women went to the tomb. Look at John's clever writing he's putting this little hint in his text for us all to read...Easter Sunday was the first day of a NEW week ... well duh its Sunday. Yes this is obvious, but there is something just a little deeper going on...its the first day of a NEW week.
Think about it this way, God created the world in 6 days, and on the 7th he rested; this was our reality, the 7th day. God's work was finished on earth. Then Jesus comes, lives, dies, and is resurrected. Christians believe that through his acts a NEW reality was fashioned; a new week was started. No longer are we living in the OLD week, but a NEW one. A NEW reality that dawned on that Easter Sunday all those years ago!! A reality that has been defined by the life, death, and resurrection of Jesus.
He has Risen!!! Welcome to the NEW week!
