This question is asking which commandment has a promise attached to it. The options are respecting parents, keeping the Sabbath, not taking the name of the Lord in vain, and not coveting our neighbor's house.

The correct answer is respecting parents, which is Option A. This commandment is found in Exodus 20:12 and Ephesians 6:2-3. It states that we should honor our father and mother so that we may live long in the land that the Lord our God is giving us. This promise of a long life in the land is attached to this commandment.

It is important to note that all of the commandments are important and should be followed, but this question is specifically asking about the one with a promise attached to it. Keeping the Sabbath, not taking the name of the Lord in vain, and not coveting our neighbor's house are also commandments given by God.

Understanding the Ten Commandments is important for Christians as it helps to guide our behavior and actions in a way that pleases God. To learn more about the commandments and their significance, please read the relevant sections of the recommended textbooks.
