Have you wondered what was the difference between the Sadducees and the Pharisees? Luke told us,
“For Sadducees say that there is no resurrection—and no angel or spirit; but the Pharisees confess both” (Acts 23:8).
How the Sadducees could deny those three things, yet, still read the Bible, escapes me. However, many people read the Bible, and do not believe all that they read. Why bother reading it? The nature of the Bible is that you have to believe all of it, or if it has faults, throw it away.
The Bible affirms repeatedly that there is a resurrection, that there are angels, and that there are spirits.
