I saw this at a Youth Group musical Thursday night. Two troubled kids were told to just ask Jesus into their lives, and everything would be better. He becomes the panacea for a troubled-filled life.
Repentance is a necessary component of salvation - an indispensible one, in fact.
What bothers me about many people is that they assume that everyone who isn't as sinless as them is not walking with the Lord or is not saved. That in order to be saved a person must be as hard a worker and as sinless a person as they are.
Hey if works and sinless living are essential to maintaining your salvation then we might as well have the law back. Nobody was righteous under the law before Jesus and certainly nobody is righteous under the law after Jesus. Only Jesus met that standard.
Repent yes. Do good works in order that you can assist Jesus in saving yourself... Blasphemy. You do good works because you love Jesus and the Holy Spirit leads you in that direction. You don't do them because you have to in order to be saved.
