Resist the sinful thoughts using Word of God
When was the last time you won a battle against sin? Do you remember or it hardly happens?
Many times even the so called experienced believers may fail the test aganist sin big time. It is because we don't follow the teaching of Christ seriously. We don't use the Word of God to resist the sinful thoughts and circumstances created in favor of satan.
We need to remember that satan leave us alone only when we believe in the Word of God and uses it against sinful thoughts. Nothing dares him more than God's word.
