Passover Prophecy
God is sovereign over the schemes of man and uses them for the salvation of His people. In John 11:47-57, Caiaphas accidentally prophesized the Gospel whiles scheming to put Jesus to death, and this fulfilled what had already been written in the Old Testament. There is no scheme or plot over which God is not sovereign, and He works all things for good for those who love Him and are the called according to His purpose.
