21:1-22:1 – ‘Satan stood up against Israel…’ (21:1). ‘Satan’ is ‘the devil’ (Revelation 12:7). He is a powerful enemy. We must not underestimate him. In the service of the Lord, we face strong opposition. It is not merely human – ‘our struggle is not against flesh and blood’. It is much more powerful – ‘the spiritual forces of evil in the heavenly realms’ (Ephesians 6:12). Satan is very powerful. When he wins a victory over you, confess your sin to God and seek His forgiveness, believing that ‘His mercy is very great’ (8,13). Be careful not to overestimate Satan. Christ is more powerful (Colossians 2: 13-15; Hebrews 2:14-15; 1 John 3:8). Christ has won the victory. In Him, we have the victory – ‘they have conquered him by the blood of the Lamb’ (Revelation 12:10-11). Keep reminding Satan of Christ’s victory. Don’t let him forget it!
