The main message of the Bible is not difficult to understand. It describes God’s purpose, why we die, and how we can be saved from death by resurrection to eternal life in the future when the kingdom of God is established on the Earth.
We all die because we sin. Sin is the disobeying of God’s commandments. We can have our sins forgiven and be raised to eternal life when Jesus returns if we believe and obey the gospel preached by Jesus and his apostles. Jesus is the Son of God and the Saviour promised in the Old Testament. He lived a sinless life and gave it in sacrifice for the remission of sins of those who will believe and obey the gospel. God raised him from the dead and he ascended to heaven to await the day appointed for his return.
The best way to read the Bible is by using a daily reading plan. The plan below goes through the Old Testament once and the New Testament twice in one year.
The Bible is to a large extent self-interpreting by use of cross references. A Bible with cross references is therefore helpful. Because the English Bible is a translation, one with access to Strong’s Concordance is very useful because it allows us to see how the original Hebrew and Greek are used and translated elsewhere. One Bible passage will throw light upon another.
The Bible is comprised of books written by inspiration of God.
2 Timothy 3:16 All scripture is given by inspiration of God, and is profitable for doctrine, for reproof, for correction, for instruction in righteousness: 17 That the man of God may be perfect, throughly furnished unto all good works.
All books have therefore equal authority. Any seeming contradictions arise from our own lack of understanding.
