What is the relationship between grace and obedience?

The relationship between grace and obedience is integral to Reformed theology. Grace is the means by which believers are enabled to obey God's commandments, not the result of their merit. Hebrews 8:10 speaks of God's promise: 'For this is the covenant that I will make with the house of Israel... I will put My laws into their mind, and write them in their hearts.' This indicates that obedience originates from God's grace, which transforms the heart and mind of His children. Thus, our subsequent actions of obedience are, in fact, manifestations of His grace at work within us, ensuring that we can never claim credit for our righteousness but must attribute all to His sovereign and gracious action.
