What does the Bible say about obeying Christ's commands?

In Luke 6:46-49, Jesus poses a critical question: 'Why do you call me Lord, Lord, and do not do what I say?' This highlights the persistent issue of professing faith without practicing it. The passage illustrates that genuine faith must manifest in obedience, as the follower who hears and acts on Christ's words builds a house on a rock, ensuring stability amidst trials. Conversely, those who merely profess faith, yet do not obey, are likened to a house built on sand, which ultimately falls under pressure. This teaches us that obedience is the only true evidence of saving faith, and it is a necessary mark of those indwelt by the Holy Spirit.
