There is One God
I believe there is one God, holy and perfect (see Revelation 1:8). The Lord God is one God, three Persons (commonly referred to as the “Trinity”) consisting of God the Father, God the Son Jesus, and God the Holy Spirit (see John 1:1).
Heaven and Hell
God himself is not created, but he created the heavens and the earth in six literal days (see Colossians 1:15-16). God created humankind through Adam and then Eve, in his image, thus giving inherit worth to all of humanity (see Genesis 1:26). The world God created was good, but sin entered the world when Adam and Eve disobeyed God’s command and ate from the tree of knowledge of good and evil (see Genesis 3:1-7).
Because of sin entering the world through the disobedience of God’s righteous law, the earth is cursed and we are separated from God (see Isaiah 59:2). God hates sin, and sinners cannot be in communion with him without being destroyed by his Holiness (see Hebrews 12:28-29).
Heaven and Hell are real places, and once we die we will be judged by God for our life on earth (see Revelation 20:12-15). Every person who does not repent and trust in Jesus for their righteousness will not go to Heaven but will go to Hell (see John 3:18).
The Life of Jesus
Jesus Christ is simultaneously completely God and completely human (see Philippians 2:5-7). Jesus is God’s only Son, who came to earth to save humankind because he loves us (see John 3:16). This was God’s plan all along, this was not a mistake (see Ephesians 3:9-11).
The Messiah, the Christ, the Savior of the world was prophesized about in the Old Testament portion of the Holy Scriptures. Jesus fulfilled all of the prophesies, including being born of a virgin through God’s promised lineage, tracing back to Abraham (see Isaiah 7:14, Matthew 1:18).
Jesus lived a perfect, sinless life on earth, leading his twelve disciples, and preaching to and serving thousands of people (see 1 Peter2:22). Jesus died an unjust death and was crucified on a cross and was buried, but he was resurrected three days later (see John 20:13-18).
Jesus is coming to earth again, for the final judgment (see Revelation 19:11-16).
Salvation through Jesus
Every human on earth has sinned, or disobeyed God, and the punishment of sin is death (see Romans 6:23). There is nothing we humans can do on our own to be good enough to deserve heaven (see Romans 3:10-12).
However, God’s plan from the beginning was to save his people by sacrificing himself to take our punishment and credit his righteousness to those who trust in Jesus (see John 3:16). Jesus Christ’s crucifixion on the cross is the ultimate, complete, and only acceptable payment for our sins (see Romans 3:21-25). The only way we can go to heaven is by confessing our sins to God through prayer, repenting (turning from a lifestyle of sin and forfeiting our right to be lord of our life), and believing in Jesus (see Mark 1:15).
It is by God’s grace alone through faith in Jesus Christ alone that any human is saved (see Ephesians 2:8-9).
Christianity is a Relationship, not a Religion
Before the crucifixion, God’s people had many laws to obey and sacrifice rituals to perform in order to be in temporary right standing with God (see Leviticus 4:35). However, these rituals weren’t what saved them from an eternity separated from God (Hell), it simply pointed to the coming of Jesus who would pay the debt of their sin once and for all (see Hebrews 10:1-10).
Now that we are living on the other side of Jesus’ crucifixion and resurrection, we are under what is called the “New Covenant” with God (see Hebrews 7:22-25). All who repent and place their faith in Jesus have the gift of the Holy Spirit, who helps believers abide in Christ and follow him daily (see John 14:15-17). Obedient believers participate in water-submersion baptism following their salvation (see Acts 22:16).
Christians live a life drawing near to the Lord, not to try and earn favor from God, but because they have been made born again and have a new desire to know him (see 2 Corinthians 5:17). While believers still battle their sin nature (also known as “flesh”), they are constantly being sanctified by the Holy Spirit, and through the power of Christ are able to follow his commands (see 1 Corinthians 6:11).
Christians maintain their relationship with God through the Holy Spirit’s indwelling in them, constant prayer to God alone, and reading the Holy Bible (see 1 Thessalonians 5:16-18). The Bible (consisting of 66 books) is God’s perfect, infallible word that has everything we need for knowing who God is and for living a life devoted to Jesus (see 2 Timothy 3:16-17).
I have been crucified with Christ. It is no longer I who live, but Christ who lives in me. And the life I now live in the flesh I live by faith in the Son of God, who loved me and gave himself for me. (Galatians 2:20, ESV)
