How do we know that imagination affects our spiritual lives?

John Newton reflects on the power of imagination and its ability to distract us from serious spiritual truths. He observes that while our imagination can create joyous anticipations, it can also plunge us into a 'fool's paradise,' drawing our attention away from the deep realities of our spiritual life, such as the end times or the judgment of Christ. This highlights the importance of vigilantly guarding our thoughts and ensuring they align with Scriptural truths, as unbridled imagination can foster inner conflict and spiritual complacency, veiling the better understanding of our eternal destiny.
