Christ Died Once For All Sins
Hebrews 9 includes a great explanation of how the new covenant sealed in the blood of Jesus replaces the old covenant established by God through Moses. The writer ends with these words:
And just as each person is destined to die once and after that comes judgment, so also Christ died once for all time as a sacrifice to take away the sins of many people. He will come again, not to deal with our sins, but to bring salvation to all who are eagerly waiting for him.
