“Thus it is written, that the Christ should suffer and on the third day rise from the dead, and that repentance and forgiveness of sins should be proclaimed in his name to all nations, beginning from Jerusalem.”
(Luke 24:46-47)

It’s Sin If You Don’t Love God With Your Whole Heart And Your Neighbor As Yourself

The concept of sin comes from the Greek word hamartia. It’s an archery term that means “to miss the mark.” Now the thinking person’s going to ask: What mark do we miss?

Answer: The perfect righteousness of Jesus Christ. Here then from Christ Himself is a concise definition of sin:

Jesus answered, “The most important is, ‘Hear, O Israel: The Lord our God, the Lord is one. And you shall love the Lord your God with all your heart and with all your soul and with all your mind and with all your strength.’” (Mark 12:30)

The reason why the above defines sin for us is because anyone who does not live up to this greatest of the commandments with all his heart at every moment, sins—period.

For you see, Jesus—the God-Man—is the only One Who could ever have fulfilled this commandment. The fact is, as mere humans, the moment we take a breath we will fail this miserably.

Maybe now you will see how awful and dreadful our peril, but O how merciful and awesome our God is to have condescended to come and live this out for those who will repent and believe.

However on the other hand it should now become patently obvious that, because all of us fail to fulfill those commandments, there simply is absolutely no such thing as a life good enough to merit heaven.

Accept God’s love and His grace in Jesus Christ, or be judged by that above Law. If we really do love God and our fellow man then we must return to preaching Jesus Christ and Him crucified…
