And all that dwell upon the earth shall worship him, whose names are not written in the book of life of the Lamb slain from the foundation of the world. If any man have an ear, let him hear. ( Revelation 13:8-9 )
If God knew the consequences of making creation before he created it but he chose to create it anyway, it means that the sacrificial death of Jesus Christ on the cross at Calvary was Plan A, not Plan B.
