If I'm Covered By Endless Grace Than Why Shouldn't I Sin?

If we are covered by endless grace does that mean we can sin as much as we want? Many people try to use God's endless grace as an excuse for their sin.

They say "Yeah I know I'm living in sin but God will just forgive me so it doesn't matter." That is not how we are supposed to use God's endless grace!

We see this same thing come up multiple times in Romans 6.

"What shall we say, then? Shall we go on sinning so that grace may increase? By no means! We are those who have died to sin; how can we live in it any longer?" - Romans 6:1-2

These verses show how flawed a way of thinking like "I sin more so God can give out more grace" can be.

"What then? Shall we sin because we are not under the law but under grace? By no means! Don’t you know that when you offer yourselves to someone as obedient slaves, you are slaves of the one you obey—whether you are slaves to sin, which leads to death, or to obedience, which leads to righteousness?  

But thanks be to God that, though you used to be slaves to sin, you have come to obey from your heart the pattern of teaching that has now claimed your allegiance. You have been set free from sin and have become slaves to righteousness." - Romans 6:15-18

We as humans are slaves to sin. Without Christ, when we are faced with the option to sin or not to sin we have no choice but to sin because of our human sin nature. That's what slaves to sin mean. Sin had us in a jail cell and we could not escape but Jesus broke open the door.

God saved us from sin not to sin. In other words, God saved us from our sin so we could be free, He didn't save us to sin or so we could sin as much as we want.

When we decide to sin it's like saying I'd rather be in a literal jail cell if I can have my sin than be free with Jesus who loves me so much He died for me. Think about that.
