God has a great purpose for us.
The life of holiness is not an expression of our own moral virtue. It is an expression of the holy character of God being reproduced in us: 'I am the Lord who sanctify you' (Leviticus 20:8). God wants us for Himself - This is why we must not live the world's way: 'I the Lord am ... holy, and have separated you from the peoples, that you should be mine' (Leviticus 20:26). God has a great purpose for us: 'You shall inherit their land... I will give it to you, a land flowing with milk and honey' (Leviticus 20:24). 'The grace of our Lord was poured out on me abundantly... in Christ Jesus' (1 Timothy 1:14). This is the pathway to holiness: 'By grace you have been saved through faith... for good works' (Ephesians 2:8-10).
