God is the creator and ruler of the universe. He has eternally existed in three personalities; Father, Son, and Holy Spirit. These three are co-equal and are one God.
(Genesis 1:1, 26, 27, 3:22; Psalm 90:2; Matthew 28:19; 1 Peter 1:2; 2 Corinthians 13:14)
ABOUT JESUS CHRIST
Jesus Christ is the Son of God. He is co-equal with the Father. Jesus lived a sinless human life and offered Himself as the perfect sacrifice for the sins of all people by dying on a cross. He arose from the dead after three days to demonstrate His power over sin and death. He ascended to Heaven's glory and will return again some day to earth to reign as King of Kings, and Lord of Lords.
(Matthew 1:22, 23; Isaiah 9:6; 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)
ABOUT THE HOLY SPIRIT
The Holy Spirit is co-equal with the Father and the Son of God. He is present in the world to make men aware of their need for Jesus Christ. He also lives in every Christian from the moment of salvation. He provides the Christian with power for living, understanding of spiritual truth, and guidance in doing what is right. He gives every believer a spiritual gift when they are saved. As Christians we seek to live under His control daily.
(2 Corinthians 3:17; John 16:7-13, 14:16, 17; Acts 1:8; 1 Corinthians 2:12, 3:16; Ephesians 1:13; Galatians 5:25; Ephesians 5:18)
Salvation is God's free gift to us but we must accept it. We can never make up for our sins by self-improvement or good works. Only by trusting in Jesus Christ as God's offer of forgiveness can anyone be saved from sin's penalty. When we turn from our self-ruled life and turn to Jesus in faith we're saved. Eternal life begins the moment one receives Jesus Christ into His life by faith.
(Romans 6:23; Ephesians 2:8,9; John 15:6; 1:12; Titus 3:5, Galatians 3:26, Romans 5:1)
ABOUT ETERNAL SECURITY
Because God gives us eternal life through Jesus Christ, the true believer is secure in that salvation for eternity. If you have been genuinely saved, you cannot "lose" it. Salvation is maintained by the grace and keeping power of God, that gives us this security.
(John 10:29,30; II Timothy 1:12; Hebrews 7:25; 10:10,14; I Peter 1:3-5)
People were created to exist for eternity. We will either exist eternally separated from God by sin, or eternally with God through forgiveness and salvation. To be eternally separated from God is Hell. To be eternally with Him is eternal life. Heaven and Hell are real places of eternal existence.
(John 3:16; 2:25; 5:11-13; Romans 6:23; Revelation 20:15; Matthew 1:8; 2:44-46)
