Ephesians 4:18

Here Paul traced the attitude of typical unsaved Gentiles to its source. Lack of worthy purpose rests on unclear understanding (cf. Romans 1:21; 2 Corinthians 4:4). This in turn results from separation from the life that comes from God (cf. Ephesians 2:12). Separation arises from natural ignorance of God (cf. 1 Peter 1:14). That in turn rests on insensitivity to God and His ways (cf. Romans 1).
