to know this love: The Christian life is based on experiencing and personally knowing God's grace and love through Jesus Christ (see Romans 12:1).
that surpasses knowledge: Christ's love is much greater than ordinary human love (see Romans 5:6–8).
A believer's life becomes complete when filled with the fullness of life and power through Christ's presence (see Ephesians 1:23; Galatians 2:20; Colossians 1:27). The believer then conforms to his image and reflects God (see Ephesians 4:14, 24; 5:1–2; Romans 8:29; 2 Corinthians 3:16–18).
