Different Christian traditions have slightly different beliefs about what the Bible teaches, but this is what I believe:
Scriptures
The Scriptures of the Old and New Testament are verbally inspired by God and inerrant in their original writings. The 66 books of the Old and New Testament are God’s complete and sufficient revelation and therefore carry God’s authority for the total well-being of mankind (Psalm 119:97-104, 160; Matthew 5:18; John 5:46-47, 2 Timothy 3:15-16).
God
The Godhead eternally exists in three persons: the Father, the Son and the Holy Spirit. These three are one God, having precisely the same nature, attributes, and perfections and are worthy of precisely the same honor, confidence, and obedience (Mark 12:29; John 1:1-4; Matthew 28:19-20; Acts 5:3-4). God created all things (Revelation 4:11) and upholds all things by the word of His power (Hebrews 1:3).
Jesus Christ
Jesus is the manifestation of God in the flesh. He was conceived by the Holy Spirit and born of the virgin Mary. Jesus is 100% God and 100% man, sinless, perfect, and the Savior of the world (John 1:1, 14,18; 14:8-9; 1 Timothy 3:16).
Salvation
Salvation is a beautiful gift of grace from God to an unworthy and sinful people. It is only through Christ’s sacrifice that we can be made right with God. No amount of good on our part can save us. An individual is saved by grace alone through faith in Jesus Christ alone. All those who have truly put their faith in Christ are eternally secure (Ephesians 2:8-9; Romans 5:8; Romans 8:38-39, John 14:6).
The Gospel (Good News)
The Gospel is that Christ died for our sins according to the Scriptures, and that He was buried, and that He rose again on the third day. After His resurrection, the Lord Jesus Christ ascended into Heaven and He is presently the believer’s High Priest and Advocate before God the Father. Because Jesus Christ rose from the dead we as believers have hope that we too will be raised to eternal life to be with God for all eternity (1 Corinthians 15:3-4, 20-22;, Acts 1:3,9; Hebrews 7:25-26).
