What does the Bible say about the church in the wilderness?

The church in the wilderness, as mentioned in Acts 7:38, refers to the assembly of Israelites who were guided by God during their journey out of Egypt. This assembly was marked by its calling upon the name of the Lord and receiving His commandments at Mount Sinai. This historical context illustrates the continuity of God's people from Abraham through to the present day church, emphasizing that the church has existed since the time of the patriarchs, providing a foundation for understanding our current relationship with God through Christ.
