The scriptures of the entire Bible are verbally inspired of God. It was not just the ideas that were inspired; even the choice of words was inspired as the original writers were moved by God to write what he wanted them to say. 2 Timothy 3:15-17
2.) The Salvation of man through Jesus.
The restoration of relationship between God and fallen mankind is the central message of the Bible. The entire store from Genesis to Revelation points to a God who loved fallen mankind so much that he gave His Son to die that those who believe in Jesus Christ and his work of providing salvation might have never-ending spiritual life. John 14:6-7
3.) The Trinity
There is one God, eternally existent in three persons; Father, Son, and Holy Spirit. These three are coequal and coeternal. 1 John 5:7 and Matthew 3:16-17
