Many "Christian" groups teach that Christianity is a new set of rules, in addition to the 10 commandments. These same types of people teach that Christians must add these rules to their lives and follow them perfectly in order to prove that they are "worthy" to enter heaven. Jesus addresses this mentality below:
"No one sews a patch of unshrunk cloth on an old garment, for the patch will pull away from the garment, making the tear worse. Neither do men pour new wine into old wineskins. If they do, the skins will burst, the wine will run out and the wineskins will be ruined. No, they pour new wine into new wineskins, and both are preserved." Matthew 9:16-17What I believe Jesus is actually saying here is that a person "will explode" if they try to look at all of these things as new rules.
Instead, he is telling us that our whole way of looking at things needs to change; our worldview and perspective needs to change. We are to live our lives "dependent" on the rock, which is Christ. We need to ask Him to help us embrace His worldview in order to overcome the storms in this life. We need to let Jesus be the filter through which we see the world. Seek to look beyond the "rules" to the "principles" of the "one" who created them. Seek to know and love "His character".
