Genuine transformation to a person's character only comes from the Gospel. There are many cults and false teachers out there that would tell you that you can attain salvation by doing works and by being a good person. This is not so. All throughout the Bible, it is very clear that there is no one that's righteous, no, not one and that we need a savior. Our righteous deeds are as filthy rags before God so we must lean on Christ’s sacrifice for our sins. When you truly receive this truth, humility will flood your life.
