“Therefore, my friends, I want you to know that through Jesus the forgiveness of sins is proclaimed to you. Through him everyone who believes is set free from every sin, a justification you were not able to obtain under the law of Moses.” Acts 13:38-39
Paul preaches to Jews and God-fearing Gentiles (v.26). After reminding them of their history (v.16-26), Paul declares what they must have known – they hadn’t obtained justification by obeying the Law. They still felt guilty. Justification is a gift we receive when we believe Jesus achieved our forgiveness. We can never do enough to earn it.
