One enemy we should focus on as Christians is our flesh. We need to deal with the works of the flesh in our lives. Hebrews 12:4 says Ye have not yet resisted unto bloodshed, striving against sin. The grace is available to overcome sin. Satan's aim is to prevent us from making heaven and partake with him in hell. When we suppress the flesh and sin, it will be much easier to overcome Satan and his hosts. We need not fear Satan and his hosts. The word, the blook and power of the Holy Spirit are available (Revelation 12:11).
