How long did Adam and Eve resist the slithering snake? A complete stranger who came into the garden uninvited and told vicious lies about God, their loving father. Did they hold out for 15 minutes? An hour? We know that they didn't survive the first encounter with Satan's lies. Many of us don't either.
God knows that about us. He's been watching people for thousands of years. That's why not only did God send His Son to pay for human sin and folly, but he also sent Holy Spirit to move into us Christians to guide us into all truth. As it Sundays in John 16:13.
We have a built in lie detector. Holy Spirit. He reveals lies to us. Lies are like snake bites. It's not enough to chase away the snake. The poison is in us. We need an antidote. God's word is the antidote. We take it by putting God's word in our mouth.
If you declare with your mouth Jesus is Lord and believe in your heart that God raised him from the dead, you will be saved. Romans 10:9. Declaring God's word builds our faith. Faith in God destroys the faith we had in the lies. Habitually answering lies with God's word is a powerful tool to silence the lies of the devil and set us free from their poison.
