Most religions in the world teach that one must work for one’s salvation by overcoming sin. We are expected to do this by following a system of laws alone (Quran, Dharma, Talmud, etc.) to qualify as a “good person.” Christianity is different in that we are rescued from slavery to sin (John 8:34, Rom 6:6-20) because we cannot escape it on our own. It’s the Holy Spirit that was promised to circumcise our hearts (Deut 30:6, Jer 4:4, Ez 36:25-27, Joel 2:28-32, Acts 2:16-21, Rom 2:29, and Col 2:11) so that we can accomplish the task of keeping God’s commands. Lastly, the Holy Spirit is only available to those who have received Jesus as Lord (John 14:15-17, Rom 8:5-11).
