Without God’s favor, His strength, no Christian can survive any satanic attack. God’s favor is seen in the Holy Spirit living inside the believer. Jesus said in the Book of Luke…
[Luke 10:19] 19 “Look, I have given you the authority to trample on snakes and scorpions and over all the power of the enemy; nothing at all will harm you.
“authority” Refers to the power of God in the name of Jesus. Only Christians have it.
“trample on snakes and scorpions” The Lord has given the believers the power, by His Spirit, to defeat the demonic spirits who are described as snakes, and scorpions. Snakes and scorpions are dangerous venomous animals that with one bite can cause pain and death.
