What you dwell on

As Martin Luther said, ‘You can’t stop a bird flying overhead, but you can stop it nesting in your hair.’ The way to get wrong thoughts out is to get right thoughts in. Your mind cannot be unoccupied. If you don’t occupy your mind with good thoughts the enemy will fill it with bad ones. Follow Paul’s advice: ‘you’ll do best by filling your minds and meditating on things true, noble, reputable, authentic, compelling, gracious – the best’ (v.8, MSG). He realises that what you think about will affect every area of your life. Fill your mind with good things, whatever ‘is excellent and praiseworthy’ (v.8). Think about what you think about. The root of our problems may be our thought life. If you change the things you allow your mind to dwell on, ‘God, who makes everything work together, will work you into his most excellent harmonies’ (v.9, MSG). The hardest part is always putting all this ‘into practice’ (v.9). The only way of learning any skill, trade or sport is by practising. Practise avoiding quarrels, staying united with other Christians (vv.2–3) and avoiding anxiety by continual prayer. If you do, then Paul promises that ‘the God of peace will be with you’ (v.9).
