Chuck Smith says the following regarding praying in harmony with God's will:
By choosing to use you to do His will, God is giving you the blessed opportunity of knowing the joy of working together with Him. Then, as results begin to take place, He rewards you as though you did the work!
When you get to heaven you'll be rewarded for those accomplishments, even though it was God who did the whole thing!
Mordecai told Esther, "For if you remain silent at this time, relief and deliverance for the Jews will arise from another place, but you and your father’s family will perish." (Esther 4:14)
When we fail to do God's will, deliverance will come from another place. We lose the blessing and reward of being a co-laborer with God, but God's program and purpose will not fail.
God wants to work in your life and bless you!
He is waiting for you to come into alignment with His plan. The moment your life comes into harmony with the purposes of God, you become the instrument through which God's power and love can flow to a needy world.
