Sorting through various translations is a starting point in our endeavors to unfold the accurate interpretation of Hebrews 9:28. Another key we can apply is to consider the harmony of this verse with scriptures relating to the same subject.
According to I Corinthians 5:7 Christ our passover is sacrificed for us. His sacrifice was the complete and final sacrifice for all sin. I Peter 1:19 says he was as of a lamb without blemish and without spot. He had to be without sin in order for his sacrifice to atone for the sins of mankind. This agrees with Hebrews 4:15 which states he: was in all points tempted like as we are, yet without sin.
In the "Lamsa Bible" Dr. George M. Lamsa, the Aramaic scholar, whose native tongue was Aramaic, translated Hebrews 9:28 from Aramaic Manuscripts:
28 So Christ was once offered to bear the sins of many; so that at his
second coming he shall appear without our sins for the salvation of
those who look for him.
The Holy Bible from Ancient Eastern Manuscripts (Nashville, Tenn.: A.J. Holman, 1957)
When God raised Jesus Christ from the corruption of the grave, his sacrifice for the sins of mankind was complete, and he was given a new spiritual body. At his second coming, he will appear in this new body for the gathering together and the first resurrection of mankind. At this time, those who have accepted him will receive deliverance from the corruption of the grave (the "salvation" spoken of in vs 28) and a new body like unto his:
...it doth not yet appear what we shall be: but we know that, when he
shall appear, we shall be like him; for we shall see him as he is. I
Who shall change our vile body, that it may be fashioned like unto his
glorious body, according to the working whereby he is able even to
subdue all things unto himself. Philippians 3:21
Another verse in the immediate context fits perfectly with the verses we have just covered ...he appeared to put away sin by the sacrifice of himself. Hebrews 9:26 This understanding fits harmoniously with verse 28 and with the many verses regarding Jesus' sacrifice and victory over sin and death and reminds us we have a glorious future to look forward to.
