The term resurrection means to rise again from death to life. It is used in Scripture (1) of those restored from physical death to life in natural form (e.g., John 11:43-44) or in glorified form (Philippians 3:21), and (2) of those who have risen from spiritual death to spiritual life through faith in Christ (Ephesians 2:5-6) (see also REGENERATION). The biblical idea of the resurrection of the body is clearly distinct from the Greek idea of life after death. The Greeks believed in the immortality of the soul but ridiculed the Christian doctrine of bodily resurrection. They believed that the body was a prison house of the soul and thereby would restrict the soul in the afterlife (cf. Acts 17:18, 32; 1 Corinthians 15:12-20). The bodily resurrection for believers involves a changed body conformed to Christ's risen and glorified humanity (Philippians 3:21; cf. Romans 8:23; Ephesians 1:14) (see also GLORIFICATION, of the redeemed). There remains a continuity as well as certain contrasts between the buried natural body and the resurrected, glorified body (John 20:25-29; 1 Corinthians 15:36-38, 49-57 (cf. Matthew 22:30).
