Proving Free Grace Is The Gospel? Romans?

What really bugs me is people claiming to be bible believers and yet they change the word of God on a whim.

2 Timothy 2:15 Study to shew thyself approved unto God, a workman that needeth not to be ashamed, rightly dividing the word of truth.

Acts 17:11 These were more noble than those in Thessalonica, in that they received the word with all readiness of mind, and searched the scriptures daily, whether those things were so.

Here we will be going over the foundation of "God through his perfect written word" Being the final authority. When someone makes a statement of faith does it line up with the Scriptures. Get your King James Bible's out and follow along.
