I believe Janie is referring to the fact that no matter how wary and suspicious she has become of men and the world around her, Tea-Cake was a breath of fresh air. He became Janie's spring.... her gift from God, and he made her feel alive again.
"All next day in the house and store she thought resisting thoughts about Tea Cake. She even ridiculed him in her mind and was a little ashamed of the association. But every hour or two the battle had to be fought all over again. She couldn't make him look just like any other man to her. He looked like the love thoughts of women. He could be a bee to a blossom--a pear tree in blossom in the spring. He seemed to be crushing scent out of the world with his footsteps. Crushing aromatic herbs with every step he took. Spices hung about him. He was a glance from God.
