Irrespective of the plans in a man's heart, God's purpose will prevail.
You and I have many plans. Unless these plans are aligned with the will of God they are bound to lead to failure. It is only God's plans that stand in the fullness of time. God's plans are accompanied by the provision of all that is needed for them to come to pass
So rather than work out your own plans, spend time in God's presence downloading His plans and understanding His purpose. Then work out His plans. One of the ways that you work out His plans is praying those plans into manifestation.
