How do we know that grace guarantees liberation?

Grace, through Christ's redemptive work, provides not only remission of our sins but also full liberation from the bondage of sin and its effects. Romans 8:31 explains that if God is for us, who can be against us, highlighting that His grace empowers us to overcome the debt of sin. Furthermore, grace allows individuals the choice to remain in loving servitude to Christ, echoing the biblical concept of manumission where one freely chooses to serve their master. This duality demonstrates that grace does not simply release us from obligation but bestows upon us the freedom to serve God willingly.
