We are to ‘use the things of the world’ without becoming ‘engrossed in them’ (31).
Becoming more worldly in our way of living is not a purely personal thing. We harm other people ‘for whom Christ died’. They look to us for a godly example and we let them down. We ‘sin against them’. We ‘sin against Christ’. Our choices affect other people. We choose a self-centred life. We cause them to ‘fall into sin.’ We live a life of ‘love’, and they are ‘built up’ in their faith (11-13,1; Matthew 18:5-7, 10).
How are we to live? Are we to become preoccupied with how our actions affect those who watch our every move? That could become very confusing and distracting. We must keep our eyes on Jesus. We must live ‘not ... as men-pleasers, but as servants of Christ, doing the will of God from the heart...’ (Ephesians 6:6-7).
