Luther, Lockdown, Law & Gospel | Galatians 5:3-4

Can anything worse be said against the Law? If you think Christ and the Law can dwell together in your heart, you may be sure that Christ dwells not in your heart. For if Christ is in your heart He neither condemns you, nor does He ever bid you to trust in your own good works. If you know Christ at all, you know that good works do not serve unto righteousness, nor evil works unto condemnation. I do not want to withhold from good works their due praise, nor do I wish to encourage evil works. But when it comes to justification, I say, we must concentrate upon Christ alone, or else we make Him non-effective. You must choose between Christ and the righteousness of the Law. If you choose Christ you are righteous before God. If you stick to the Law, Christ is of no use to you.
