This song talks about how when she first became in the music industry she was faced with a big decision to get an abortion. Her career was on the line and people tried to convince her that it would be better for her.
Then it was like deja vu when her whole mindsetting changed towards the whole situation. She was bewildered of what she was thinking of doing beacuse it would change her life for better or for worse.
So she decides to keep the baby, named Zion, and she is "in love" with her newborn. Instead of bringing her stress he brought her joy.
How beautiful if nothing more
Than to wait at Zion's door
^ She can't be more happier to be the mother of this child
Zion basiclly brings her all the joy and happiness that nothing else can bring.
