"Now there was a famine in the land--besides the earlier famine of Abraham's time--and Isaac went to Abimelech king of the Philistines in Gerar. The LORD appeared to Isaac and said, "Do not go down to Egypt; live in the land where I tell you to live. Stay in this land for a while, and I will be with you and will bless you."
When there was a famine in Abraham's time, he went to Egypt for food. But God asked Isaac to stay where there was a famine and promised to take care of him. It would take faith for Isaac to stay in spite of what he saw around him. He did stay and God blessed him.
"Isaac planted crops in that land and the same year reaped a hundredfold, because the LORD blessed him." Genesis 26:12
If God asks us to do something for him, He will also supply our needs. He has done that for Desiray in her park ministry. So, even if we don't have the resources, He will help us get them.
