Jesus Christ is God's Son. He was born of a virgin as both God and man, lived a sinless life, died to atone for the sins of human beings, was buried, arose from the grave, ascended into heaven, and will literally return to earth (Matthew 1:22–23; Isaiah 9:6; 53:5–6; John 1:1–5; 14:10–30; Hebrews 4:14–15; 1 Corinthians 15:3–4; Romans 1:3–4; Acts 1:9–11; 1 Timothy 6:14–15; Titus 2:13).
The Holy Spirit is the divine helper, assistant, counselor and instructor and His work is to reveal Christ, convict of sin, lead to repentance, guide believers, comfort, strengthen, and sanctify the soul (2 Corinthians 3:17; John 16:7–13; 14:16–17; Acts 1:8; 1 Corinthians 2:12; 3:16; Ephesians 1:13; 5:25; Galatians 5:25).
Salvation is a gift through repentance toward God and faith in Jesus Christ. Every person who truly is saved is eternally secure in the Lord Jesus Christ and will spend eternity in heaven, while those who die in their sins will spend eternity in hell (Romans 6:23; Ephesians 2:8–9; John 14:6; 1:12; Titus 3:5; Galatians 3:26; Romans 5:1).
