In Joshua 9 of the Bible, Israel cuts a deal with some of the people they are meant to destroy. In the process, they make their conquest -and their futures- much more difficult. This is what happens when Christians don’t do their homework and believe any story, and it ends up getting them ensnared in evil that can hinder and hurt them (2 Corinthians 6:14-16). Seeking God in all things is so critical and never settling for second-best.
Here is my Joshua 9 Bible Study (in PDF). Feel free to use it. It includes the passage from the ESV, although there are some expressions that I have changed for the sake of maintaining consistency with the Hebrew that it was originally written in.
God bless, Pastor Haydn.
