Christians receive Jesus (John 1:12) and put their faith-filled trust in what Jesus did on the cross (Isaiah 53:12; 1 Pet. 2:24) and in so doing are justified by God. The Bible states that justification is not by works (Rom. 3:20, 28; 4:5; Eph. 2:8-9) because our righteous deeds are filthy rags before God (Isaiah 64:6). Therefore, we are saved by grace alone, through faith alone, in Christ alone.
