One sacrifice for all sins means we’re forgiven, not day after day, not little by little, but once and for all!
What do you mean by “once for all” forgiveness? How do I get closer to God? How do I know I’m saved? Is there a mandated 10 percent tithe? What is your take on Matthew 23:39? Most Jews died under the Law, does that mean there is no hope for salvation for them?
