Though every other world religion teaches it, and there are many false churches under the guise of Christianity that are willing to accommodate it, the Bible knows nothing about earning God’s favor. The reason is because we can’t. God is so perfectly holy. He simply can’t accept an ounce of sin in His presence. He’s not looking to bestow eternal life on those who think they are righteous as some sort of a reward. He’s looking for those who acknowledge their own rebellion and look to Him to receive His righteousness as a gift by running to Him for complete rescue.
