Satan desires to destroy faith with his lies, which either lead to despair, losing all hope in God’s love for us OR apathy, an “I really do not care” what happens to me spiritually. Either way the lies are toxic to us spiritually leading us away from the truth that God loves us and has saved us in His Son. But just as physical toxins can take a long time to noticeably harm us and finally kill us, so spiritual toxins can take a long time to destroy faith.
