We don’t have to be always in a defensive posture. It’s not that we wait for Satan to sneak up on us. We’ve got a calling to live under Christ in his kingdom and serve him in righteousness and purity (resisting temptation). But when Satan does come our way, we can stand firm with the armor of God, and fight him just as Jesus did with God’s word.
Whether it’s praying the Psalms, reading and memorizing Scripture, or meditating on God’s word daily, Scripture is a powerful weapon against Satan and his schemes. We may fail. We may give in. That’s why Jesus’ victory is so precious. For he is our Savior. He forgives us when we fall, and empowers us to get back up and live to his glory and toward our eternal destiny – all secured in Jesus.
