‘Christ Jesus came into the world to save sinners’ (1:15). To each of us, God says, ‘Watch your life and doctrine closely’ (4:16). What we believe is important. How we live is also important. If our faith is real, it will lead to a change in our way of life. There is a great battle going on – between God and Satan. We must ‘give the enemy no opportunity to slander us’. We must take care how we live – ‘so that God’s Name… may not be slandered’ (5:14; 6:1).
Serve the Lord in the ‘power’ of ‘the Holy Spirit’ (1:7). Be ‘lovers of God’ rather than ‘lovers of self’ (3:4,2). What kind of preaching do we need? Do we need ‘teachers who will tell us what we want to hear’ (4:3)? No! We need preachers who will say ‘what the Spirit says to the churches’ (Revelation 2:7).
