I prefer to believe in concepts that include all of humanity. Doesn’t the Bible only deal with the Jewish people?
You said that you were looking for “concepts that include all of humanity.” I believe the Bible does speak to and include all of humanity. All humanity is the point of Romans chapters 1-3. Chapter 3 is the summation of the argument. The basic proposition of chapter 3 is this: the entire world is guilty because of the sin inside us. We are not “good.” We all possess a sin nature that our children inherit. That is true in both time (past humanity, present humanity, and future humanity) and space (all over the face of the earth). Paul makes the point very clearly starting in verse 9. By using the word “Greeks” he is speaking of all non-Jewish people.
Romans 3:9-18:
…we have already charged that both Jews and Greeks are all under sin; as it is written,
There is none righteous, not even one;
There is none who understands,
There is none who seeks for God,
All have turned aside, together they have become useless;
There is none who does good,
There is not even one.
Their throat is an open grave,
With their tongues they keep deceiving,
The poison of asps is under their lips;
Whose mouth is full of cursing and bitterness;
Their feet are swift to shed blood, destruction and misery are in their paths, and the path of peace have they not known.
There is no fear of God before their eyes.
Paul is quoting the Old Testament here, showing the universality of the Old Testament as well. What I have been sharing with you is God’s assessment of the world. The world would object and say, “We seek after God.” The problem lies in the fact that the world has set up its own concepts of God and that is what they truly seek. That the world does not seek a personal relationship with the true and living God is the assessment of the Bible. We can only know the true and living God, the God of Abraham, Isaac, and Jacob, through His self-disclosure (revelation). Otherwise, we are simply building on our own personal concept of God, which is inaccurate to a greater or lesser degree. That is why there are so many religions in the world.
