IMO of course not. We are members of the covenant that guarantees forgiveness of sin. GOD is faithful to his covenant when we aren't. But he does have his limits. What those are, no man knows (except for blatant denial). That's why it's prudent to fear GOD.
20 The law was brought in so that the trespass might increase. But where sin increased, grace increased all the more, 21 so that, just as sin reigned in death, so also grace might reign through righteousness to bring eternal life through Jesus Christ our Lord. (from Romans 5)
There is one boundary. You're either in Christ or in Adam. Grace is not extended to those in Adam and then rescinded from those who are in Christ.
Not only is Grace hyper, but Grace reigns through righteousness through Jesus Christ our Lord!
