[The Galatians] joined the works of the law with Christ and his grace in the cause of their justification and salvation. Here it must be observed that they which make a union of grace and works in the cause of justification are separated from the grace of God. Grace admits no partner or fellow. Grace must be freely given every way, or it is no way grace.

Here’s another Perkins quote on the same topic:
