Numbers 21:1-9. These verses speak of when the Isralites were complaining about their struggles. So much so that they spoke out against God and Moses.
God sent serpents that killed many, so the people cried out for forgiveness.
Now instead of removing the serpents God told Moses to build a statue of the snake. When the people got bitten by the snakes, they were to look up at the statue and then they would live.
You see, God is not going to remove the challenges. When they sting, we are to look to Him. In that, those things that were sent for our downfall will lose their power. We have access to this now by the blood of Jesus Christ. It is already done.
