Mat 5:17 "Do not think that I came to abolish the Law or the Prophets; I did not come to abolish but to fulfill. Mat 5:18 "For truly I say to you, until heaven and earth pass away, not the smallest letter or stroke shall pass from the Law until all is accomplished. There is a gnostic view of the scriptures today that has entered into the Christian Churches that is, literally, sending people to Hell. The single verse above, 5:17, shows the truth of the matter but it is generally, just, not considered. About 144AD, mid Second Century, Marcion prompted the notion that the Old Testament and the New Testament were in disagreement, giving birth to the heretical Gnostic idea that the New Testament has, in some fashion, superseded the Old Testament. In John 1:1-3 we find that nothing exists in the world that Jesus did not create or cause to be. And when we read Malachi, in the third chapter and the sixth verse we find God explaining that He never changes! What Jesus did for us, before the cross, was to teach us, not the letter of the Law, rather, He taught all that will listen, the heart of the Law. In the Law it is said that, Thou shalt not murder, if you do you will go to Hell. But Jesus taught us that if we hate our brother, we are guilty of murder, already! Jesus taught Christianity from the Old Testament, the New was not even being written when He was teaching and if you never study the Old Testament, the light of what Jesus had recorded for us will never shine upon the New Testament as you read it. So, you need to ask yourself, “When I read the Old Testament, is it confusing?” If it is, and it was to me before the Indwelling of the Holy Spirit, you might want to consider doing a Spiritual Inventory. I'm not trying to scare you into believing you're not saved but to find out if you've been quenching the Spirit. And if you can't find Him there, then you might want to think about why.
