Question: Why should Christians obey God's commandments?

Answer: Why should children obey their parents? The answer to this question is partially the answer to the question posed.

The purpose of obedience to God's commandments is twofold:
a) It shows that you love Yahweh your Heavenly Father in turn. Obedience is an expression of love. You cannot claim to love God while you rebel against His laws.
b) It proves that your faith in God and in Jesus is genuine. How can you claim to trust in God if you do not fear the consequences of your rebellion? While our obedience to God's laws should not be driven by fear of punishment, we would be quite foolish to think that we will escape unscathed when we willfully disobey Yahweh's laws. Failing to perfectly obey God's laws when you have tried your hardest is one thing; to willfully rebel against His laws is quite another thing. There will not be any condemnation to only sincere Christians who failed to perfectly keep God's laws. It's another story for rebels. Simply put, God will not be mocked; we reap what we sow (Galatians 6:7).

Remember: "He [Yahweh through Jesus] will judge everyone according to what they have done. He will give eternal life to those who keep on doing good, seeking after the glory and honor and immortality that God offers. But he will pour out his anger and wrath on those who live for themselves, who refuse to obey the truth and instead live lives of wickedness. There will be trouble and calamity for everyone who keeps on doing what is evil—for the Jew first and also for the Gentile. But there will be glory and honor and peace from God for all who do good—for the Jew first and also for the Gentile. For God does not show favoritism.

"For merely listening to the law doesn't make us right with God. It is obeying the law that makes us right in his sight." (Romans 2:6-11, 13, NLT)

"You say you have faith, for you believe that there is one God. Good for you! Even the demons believe this, and they tremble in terror. How foolish! Can't you see that faith without good deeds is useless? Just as the body is dead without breath, so also faith is dead without good works." (James 2:19-20, 26)

"So get rid of all the filth and evil in your lives, and humbly accept the word God has planted in your hearts, for it has the power to save your souls. But don't just listen to God’s word. You must do what it says. Otherwise, you are only fooling yourselves. For if you listen to the word and don't obey, it is like glancing at your face in a mirror. You see yourself, walk away, and forget what you look like. But if you look carefully into the perfect law that sets you free, and if you do what it says and don't forget what you heard, then God will bless you for doing it." (James 1:21-25)
