The law, earthly priests, and earthly sacrifices did not atone for sin. Christ’s sacrifice, once and for all, atoned for the sins of those who believe in Him. He serves as our High-Priest in Heaven. He is a superior priest and a superior sacrifice, since He intercedes and sanctifies us forever. We are called to live lives of faithful obedience until our lives on earth are complete, enduring through suffering, so that we can inherit the promises of God. For believers who abandon their faith and sin freely, without repentance, there will be a loss of reward and a failure to inherit the promises of God. But we are empowered by Christ, our superior priest, and the Spirit living within us, to live righteously, to endure suffering with confidence, thus doing the will of God.
