For my yoke is easy, and my burden is light.Matthew 11:30 (KJV)
Before Jesus Christ died for our sins, the path to salvation involved following the law of God completely. While it wasn’t as hard as many make it out to be, it was still too much for anyone with a man’s heart (in other words, everyone) to fulfill without succumbing to the sins that are in our nature.
Yeshua changed that. He gave us an path that not only guaranteed our salvation but that also made it easier for us to follow the law of God. This last part is important to understand. By making his yoke easy, he didn’t eliminate the burden of the yoke. We are still servants. We are still required to keep the law. Yeshua’s sacrifice simply made it easier on us to follow.
