It's no different today. Satan is still out to get the child of God. He is our enemy. In order to defeat him we must be grounded in the word, in prayer and living as close to the Lord as possible. We do not have to let Satan tread all over us. We should be the ones doing the treading.
We have the authority in the name of Jesus to stand right up to Satan and tell him in no uncertain terms that we will not accept what he is trying to do. We can rebuke him and tell him to leave in Jesus' name. There's power in the name of Jesus. If we don't use the power that the Holy Spirit gives us, we will be defeated
Jesus has already defeated Satan and it's about time for us to look at him that way. We have to stand up in the name of Jesus and show Satan that we are not taking it anymore. Satan will bring all kinds of circumstances into our lives and try to bring us down. When that happens, give the circumstances to God, refuse to be moved by them and allow him to work things out. Circumstances given to God are simply avenues where He can work His will and turn things around for His glory. He will turn it around if we let Him.
