The Overcomer was reminding us of our Father’s Love and His Kingdom. The leaven of the Pharisees and Sadducee because they believed in mankind being separated from their Creator. They were also proud of their own performance of rituals and traditions of men making the word of Christ ineffectual.
The Sadducee means the righteous and they hated the “common” people and didn’t believe in the resurrection or Angels. Jesus knocked Paul off his donkey and blinded him for 3 days for persecuting Jesus by calling the people “common..” Acts 10 and 11 … remind us Don’t call dirty, common, unclean, wicked, or unholy, or left behind on what I have cleansed. Forsaken means to be left behind and abandoned. Can’t Happen!! He said I will never leave you or forsaken you and nothing can separate you from the Father!
The Cross pictured the invisible truth of the Lamb of God who was slain from the foundation of the world. Paid for “the carnal mind that sees forsaken on the Cross when He said, My God My God why hast thou forsaken me.” That was the wicked man of sin, liar, and the false witness that shouts separated from God our Father.
His Covenant oath of Promise is everlasting, from the beginning and that cannot happen in TRUTH which is eternal reality in His rest with His perfect peace.
