There's no expiration date on this promise. It doesn't just say, "I won't turn away a sinner at the beginning," but, "I'll never cast them out." The original stresses this: "I won't, not cast out," or "I'll never, never cast out." It means Christ won't reject a believer at first, and He won't do it later either. But what if the believer sins after coming to Him?

"If anyone sins, we have an advocate with the Father, Jesus Christ the righteous." What if believers stray? "I'll heal their backsliding; I'll love them freely—my anger is turned away from them." But what if they face temptation? "God is faithful; He won't let you be tempted beyond what you can handle. He'll provide a way to endure it." And what if a believer falls into sin, like David?

Even then, He'll "purge them with hyssop, and they'll be clean; He'll wash them and they'll be whiter than snow." "I'll cleanse them from all their sins." "Once in Christ, in Christ forever; nothing can separate from His love." "I give my sheep eternal life," He says, "and they'll never perish, nor will anyone snatch them from my hand." How do you feel about this, O trembling heart? Isn't it a precious mercy that coming to Christ means you're with someone who won’t discard you but will always hold you close? Take on the spirit of adoption, not fear, and cry out, Abba, Father! Cherish these gracious words: "I'll in no wise cast out."
