I'll throw in my 2 cents worth. I believe that my sin separates me from God. Before Christ, atonement came from sacrificing at the altar in the temple. An animal was given in sacrifice in place of the person. Through the sacrifice, man was once again in the presence of God. CHrist came and became the ultimate sacrifice for everyone's sins for all time. I no longer have to sacrifice according to the law of Moses. I have to accept the sacrifice of Christ. Because Christ died for my sins, I am free to experience a personal relationship with God. I ask for forgiveness through CHrist who has already atoned for my sins. Hope this answered your questions Bekka.
P.S. I am Methodist. Baptized, confirmed, practicing.
Before you were conceived, I wanted you. Before you were born I loved you. Before you were a minute old, I would have died for you. That is the miracle of life. ~Maureen Hawkins~
