In Philippians 2.12-13 the apostle Paul counsels the church to 'work out your own salvation with fear and trembling FOR God is at work in you both to will and to do for his good pleasure'. God is at work in us; therefore, we can work out what He has already done within. Ephesians 5.1-2 sets out an important aspect of the conduct of the Christian: walk in love as Christ loved us and gave himself up for us (repeated in 5.25 to husbands). In 5.1-2 we are called to be 'imitators of God' (!): to be like our parent seeing we are his children. We, who have been loved beforehand (even when we were enemies of God, Rom 5.10) are called to walk in LOVE. ('Walk' means 'to conduct your lives' [according to the will of God].)
we look not to the things that are seen but to the things that are unseen --Paul, Apostle to the Gentiles
