In the sermon 'Preservation Is Of God' by David Green, the speaker emphasizes the fundamental belief that salvation and perseverance in faith are entirely dependent on God. He asserts that without God's intervention, individuals cannot achieve salvation or maintain their faith. The speaker underscores the idea that human efforts alone are insufficient for spiritual perseverance and that divine preservation is essential for enduring faith.

If the Lord didn't save me, the Lord doesn't save you. If the Lord hasn't saved you, if the Lord hasn't saved me, then I can't be saved and you can't be and you can't be saved. And as we think about this, it's also true that if he doesn't hold me, If he doesn't hold you, if he doesn't preserve me, if he doesn't preserve you, then we're not going to make it. There will be no perseverance.
