In Ester chapter 5.
The plan is being executed. This shows us that after praying we should spring to action. Faith without action is dead.
However it cautions that, before embarking on anything, or after realsing there is a problem. The first thing to do, even before proceeding to problem solving stage. The firts thing to do is to pray so that God is involved right from the begining and not just when things get tough.
Smtimes we go to God when problems have overwhelmed us and our solutions fail. But in Ester 5 we learn to go to God before we start looking for solutions.
