You know how the scripture says in Proverbs that the path of the just shines brighter and brighter until the perfect day? It makes us understand that there is always more as our man of God would constantly remind us.
The issue now is that, although there is always more, you must ensure to see that more and be that more. Recall the story of Abraham and how God told him to leave his country to a place he will be shown? Yes, it must have not been easy for him to leave his comfort zone but then God knew there was so much more He had in stock for Abraham. Assuming Abraham had said no, I am okay here or doubted God and his promises, he would not have been able to achieve all he did throughout his lifetime, he might not be the father of faith today. This is one clear instance of one being the “limit”. He would have limited himself and remained “normal”.
