Jesus taught Open Theism (changeable future) when he said:
1. He could pray for twelve legions of angels to deliver him from the cross (Matt. 26:53),
2. That the times of tribulation were shortened for the sake of the elect (Matt. 24:22),
3. Pray that your flight not be in winter (Matt. 24:20).
Countless other examples can be shown also of the future being changed, like:
God not making a nation out of Moses (Exodus 32),
God not destroying Nineveh in forty days (Jonah 3),
God adding fifteen years to Hezekiah’s life (Isaiah 38),
Abraham negotiating with God over Sodom and Gomorrah (Genesis 18),
God looking for an intercessor to stand in the gap so that He wouldn’t destroy them (Ezekiel 22).
The list can go on and on as Open Theism is taught from Genesis to Revelation in the Bible.
The biblical truth of open theism is simply this: God is Sovereign and can change the future. Just read Jeremiah 18.
The future is not fixed from eternity. God is the potter. We are the clay. The future is not cement. It is clay in God’s hands.
