God did provide!
Isaac spoke up and said to his father Abraham, “Father?”
“Yes, my son?” Abraham replied.
“The fire and wood are here,” Isaac said, “but where is the lamb for the burnt offering?”Abraham answered, “God himself will provide the lamb for the burnt offering, my son.” And the two of them went on together.
When they reached the place God had told him about, Abraham built an altar there and arranged the wood on it. He bound his son Isaac and laid him on the altar, on top of the wood. Then he reached out his hand and took the knife to slay his son. But the angel of the Lord called out to him from heaven, “Abraham! Abraham!”
“Here I am,” he replied.
“Do not lay a hand on the boy,” he said. “Do not do anything to him. Now I know that you fear God, because you have not withheld from me your son, your only son.”
Abraham looked up and there in a thicket he saw a ram caught by its horns. He went over and took the ram and sacrificed it as a burnt offering instead of his son. So Abraham called that place The Lord Will Provide. And to this day it is said, “On the mountain of the Lord it will be provided.”
(Genesis 22: 7-14 NIV)
Only when we accept that God gave His son for all of us on a mountain in Jerusalem, we stop sacrificing our sons for Jerusalem.
GOD DID PROVIDE !!!
