The bible is a collection of 66 books written over a period of approximately 1400-1500 years in 3 different languages across 3 continents by over 40 different authors from every walk of life (from a kings throne to prison cell). Most of whom never knew each other and many of which died a horrible death rather than deny their faith. With no historical errors or contradictions, coming together in one single unified harmonious message.
The creation, fall and redemption
Gods universal love for all humanity
A common message of salvation is available to all who repent of their sins and commit to following God with all their heart, soul, strength and mind.
