In scripture we find a righteousness by faith that did not start in the book of Matthew. Instead it starts with a covenant given to Abraham. This teaching comes from our New Testament writers.
Many a Bible believing believer has been told or left with the impression that men could not be credited righteousness until Jesus died on the cross. This anti-biblical view in reality is an imposter gospel that has replaced The Gospel According to the Gospel we find in scripture.
There is another anti-biblical view that is accepting by many a Bible believing believer. This is again the belief our gospel starts in the book of Matthew. However the New Testament writers defend a gospel that started long before the book four gospels. They defend a gospel, or as they say, our gospel that was preached in the Law of Moses and the prophets.
I have articulated over and over again three truths about the gospel we share in. The first is we are credited the righteousness that was given to our father Abraham through Christ. That those of the Old Testament had a saving faith when they walked according to the promise of this credited righteousness
The second truth is our gospel was preached at Mt. Sinai and foretold to Abraham in advance. When the Old Testament saints put their hope in our gospel they had a faith that could save them.
Some may ask, but how could they have our gospel? How could they have the same hope of Christ and salvation that we do before the cross? Well, I would like to add more evidence that our gospel was well known before the four gospels were ever written.
Jesus took the Twelve aside and told them, “We are going up to Jerusalem, and everything that is written by the prophets about the Son of Man will be fulfilled. He will be handed over to the Gentiles. They will mock him, insult him, spit on him, flog him and kill him. On the third day he will rise again.”
Jesus Himself teaches us that in the prophets we can find a gospel about the messiah who will suffer, die and be raised to life again. This is the gospel they had in the Old Testament and ironically what we have in the New Testament as well. They had the credited righteousness of Abraham just as we do today. They in the Old Testament had the hope of salvation when they believed in the gospel they had preached to them, just as we do today. Which brings me to my third scriptural truth.
There is a belief by nearly all Bible believing believers that is anti-biblical. This is the belief that men posses salvation, instead of hope for salvation as taught in scripture. Just as the New Testament teaches all believers, our God is one who speaks things that are not as if they were. Yet we reject this in our gospel and say we have what is not when it is spoken of as if it were, concerning our salvation. When then ignore the hope of salvation held out in the gospel or make up the three tenses of salvation which goes against our gospel again.
For in this hope we were saved. But hope that is seen is no hope at all. Who hopes for what he already has? But if we hope for what we do not yet have, we wait for it patiently.
We have rejected all those scriptures that speak of the hope of salvation in scripture just as we have rejected those scriptures that speak of imputed grace given to Abraham and his descendants along with all those scriptures that speak of our gospel preached in the Old Testament. It appears to me there are a lot of Bible believing believers who believe in the teachings of men more than what God has given us in scripture.
Since we have such anti-biblical beliefs in the church, and we ignore the three Biblical truths about our gospel, what good is the gospel we the church have put our hope in, since it has strayed from The Gospel According to the Gospel.
