Only Jesus could keep the commandments perfectly. It is not possible for you or I to do that. But that does not remove the obligation for us to obey God and do our best to keep them. If we say we believe in Jesus yet ignore his instruction then we are not acting in faith. We, then, are practicing sin. With this new covenant, God wrote His laws on our hearts so that we would keep them, not ignore them.
You say “That is why Christ came into the world – to save sinners.” But Jesus said “Repent, for the kingdom of heaven is at hand.” To me, that means he came to save those who sin but repent. We all sin but we don’t all repent. Those who continue to practice sin but fool themselves into believing that they don’t need to repent are treading a dangerous path.
“He who says, “I know Him,” and does not keep His commandments, is a liar, and the truth is not in him.”
You, with most of the Christian world have listened to one of Satan’s greatest lies by believing that you are under grace even when you ignore the commandments. Why did Jesus, our Lord and Savior, instruct us to keep the commandments if He didn’t expect us to obey Him? You tell me to read the teachings of Paul (of whom Peter said are “hard to understand, which the untaught and unstable distort, as they do also the rest of the Scriptures, to their own destruction.”) but why do you not focus on the clear instructions that came straight from the mouth of God? Paul, by the way, did not teach lawlessness and he kept the commandments to the best of his ability even after he became an apostle of Jesus. What did he mean when he said “Circumcision is nothing, and uncircumcision is nothing, but what matters is the keeping of the commandments of God.”? Did he not keep the weekly and annual sabbaths and, thereby, provide the example to his disciples?
The fact that we are not justified by works does not mean we can ignore the commandments. James told us that faith without works is dead. And that is the key. If you truly have faith, you will have works. If you say you believe but have no works then where does that get you?
“You believe that there is one God. You do well. Even the demons believe—and tremble!”
Just as God required an act of faith from Abraham who already believed, so, too, does He require us to act in faith by keeping His commandments. Sinning without repentance is not the way to the kingdom.
What good is knowing you’ve broken a commandment and that you are sinning, if you don’t repent of your sins? When you truly turn to God and (attempt to) keep His commandments, His Spirit will reside in you and will help you in your goal to become more like Him. When you fail, you know it, and you repent. When you stop repenting you have entered the broad road that leads to destruction. This is the road that all unrepentant sinners walk.
“If you love Me, keep My commandments. And I will pray the Father, and He will give you another Helper, that He may abide with you forever— the Spirit of truth, whom the world cannot receive, because it neither sees Him nor knows Him; but you know Him, for He dwells with you and will be in you.”
When asked “which is the greatest commandment in the law?” Jesus answered “‘You shall love the Lord your God with all your heart, with all your soul, and with all your mind.’ This is the first and great commandment. And the second is like it: ‘You shall love your neighbor as yourself.’ On these two commandments hang all the Law and the Prophets.”
But how do you love the Lord with all your heart, with all your soul, and with all your mind? YOU KEEP HIS COMMANDMENTS! (“If you keep My commandments, you will abide in My love; just as I have kept My Father’s commandments and abide in His love.”)
This Friday night at sundown begins the weekly Sabbath. At that time, I’d suggest you ask yourself why am I not observing God’s holy day instead of “fill in the blank”? Just as the Sabbath was a test for Israel in the wilderness it is a test for God’s people today. Unfortunately 99.99+% of the world is failing that test on a weekly basis.
