Replacement theology is the teaching that the Christian church has replaced national Israel regarding the plan, purpose, and promises of God. It is the idea that God dispensed with Israel because of their sin, all covenants and promises that God made to Israel are either broken or bestowed on the Christian Church. this idea stems from the Human bent towards vindictiveness and spite and the desire of humans to attribute this evil to God. an attempt to mold a God in humankind's own image. basically idolatry in it's purist form. personally I wonder why humankind wants a vindictive, spiteful God. would seem to be an obvious dead end, literally, after all, the only way one could please a vindictive god is to die, is it not? yet, it is what it is. Islam takes this same theology one step further and declares that not only is God finished with Israel, but is finished with the Christian Church as well, because of their sin, so, in their view, God is done with Israel, God is done with Christians, but God will never be done with us, because we are better than y'all, we never make mistakes, you Jews didn't "get it" you Christians didn't "get it", but we? we "got it".
see the logic? neither do I. yet, here we be. People always want to believe they have a better take/knowledge/understanding/belief/standing than their neighbor. I'm closer to God than YOU are, na, na, naa, na, na, naa....stupid.
This Idea had it's start:
Gen 3:4 And the serpent said unto the woman, Ye shall not surely die:
Gen 3:5 For God doth know that in the day ye eat thereof, then your eyes shall be opened, and ye shall be as gods, knowing good and evil.
the serpent told Eve that God was a lying, mean, vindictive cuss, and Eve, and Adam, believed him. They had two choices before them, either believe God, or believe the serpent. they made their choice. and we live with the consequences of that choice today. now we see, yeah, we have knowledge of good and evil, but to be honest, we seem to have a natural bent to choose wrong much of the time, do we not? there's something missing in our psyche it seems...
The outworking of the idea that God is vindictive has consequences, after all, If God is vindictive, cannot the followers OF God be vindictive too? this Idea has killed a lot of people in the world, and torn up nations, peoples, churches, families. waffling about this point is disastrous. ya gotta either believe God or believe the serpent, there is no middle ground. which do you choose? Prophecies point to an ultimate end of this question, there is only two sides to choose and God let that choice be you own.
