Christians are those who are united to God through Jesus Christ (2 Thessalonians 2:13). They have exercised saving faith in Jesus (John 3:15-18; Acts 4:12; 1 John 5:1) and repented of their sins (Romans 2:4; 2 Peter 3:9). God has forgiven their sins (Acts 10:43), made them His children (Romans 8:16-17), and transformed them into new creatures (2 Corinthians 5:17) indwelt by the Holy Spirit (John 14:17).
