Charlie spoke at the 2020 FGA conference about six selected common objections to Free Grace. The six objections include:

1) Free Grace is Easy Believism (aka Decisionism) - it may be simple to believe, but it's not easy. Why would God make salvation difficult?

2) Free Grace Rejects Jesus as Lord and still be saved - we don't teach this as part of salvation but we certainly teach it regarding discipleship. 

3) Free grace does not teach that a sinner must turn from sins (aka Repent from sin). - If Repentance is defined as turning from sin, then yes, we don't teach that. But if repentance is defined as a change of mind, then yes, many do teach that. Repentance isn't defined by outward actions.

4) Free grace believes a saved person does not have to show evidence of good works (James 2:14 - faith without works is dead) - Well who says that? Which works and how often, and how do you define good works? Which ones are legitimate? Good works can be evidence, but not proof. 

5) Free Grace leads to false assurance of salvation - John MacArthur publicly admitted he's 99% sure he's saved. Those who object as he does, cannot say they are 100% sure because they are basing it off of subjective assurance, not objective assurance. Our assurance is based on the power and promises of God, not based on works before nor works after salvation. 

6) Free Grace leads to license (aka antinomianism) - Antinomian means against the law. We are not against the law, but the law doesn't govern. Paul addresses license in Romans 6.
