What is your "god" in life? There is no true atheist. We all worship something. Is it self? Is it the law of Moses? The law of Moses could only condemn unbelievers.
For the believer, there is no condemnation for those who are "in Christ Jesus." (Romans 8:1) The law serves no purpose in condemning believers since as Romans 7:6 states, we have "died to the law." The law for a believer has no power to condemn us.
What does this mean? First, we have freedom. We no longer walk according to the old letter of the law - a set of regulations - but in the new law of the spirit.
Second, we walk by grace through faith. When Christ Jesus died on the cross, he, the very son of God, satisfied the law's demands. Though we died to the old letter of the law, we do not live lawless lives, for we live according to the new law of love, which encompasses the old letter. Love, for example, does not murder, steal, commit adultery, bear false witness or worship an idol. Even an atheist has an idol.
Third, we are no longer walking under a cloud of guilt. Guilt is just old, heavy baggage that weighs down the conscience. That guilt is erased once we accept personally the free gift of salvation through Jesus Christ. It was at the cross that Jesus, the son of God, bore the curse of the law. The law reveals our guilt, while grace through faith brings forgiveness.
Fourth, there is not enough good works to satisfy the law's demands. A work-based religion makes us slaves. We have to keep striving to attain a right relationship to God. Grace through faith is taking God at his word, and when we do, we are justified. Finally, confess Jesus as the son of God who shed his blood at Calvary and believe in your heart he was resurrected from the dead. We then have died to the law and its power to condemn us.
Jews and Gentiles are one in the body of Christ, but Jews have not lost their covenant promises.
