If Jesus shedding his blood on the cross as our kinsman redeemer gave us all eternal life, OT saints and the Church alike, why do we have two different rewards or destinations? OT saints will occupy Jerusalem on Earth, but the Church will dwell in the New Jerusalem, a city of gold designed just for us that no one else can enter. I know God is just, but it seems to me the Church has been more exalted than God’s chosen people from ancient times. How can we be so much more rewarded if both groups believe in the same Messiah and are saved by his blood?
Almost anywhere you look in the Old Testament you can find accounts of God providing physical, tangible evidence of His existence. The list of all the different ways in which He did this would consume pages. But the New Testament is all about faith and nothing else. Very few of us have seen even a single miracle.
Remember the story of Thomas who wouldn’t believe in the resurrection until he saw the evidence (John 20:24-29)? When the Lord appeared before him as tangible evidence he was convinced. But the Lord said, “Because you have seen me you have believed. Blessed are those who have not seen and yet have believed.”
I think it’s fair to say the Church has a better deal than any other group of believers in all of humanity, and that’s why. We have not seen and yet have believed.
