What does Paul mean to mind not high things? It cannot mean to avoid the high, deep doctrines of God which Paul himself often teaches. He says that we should condescend to men of low estate. He seems to mean that we should not talk over people’s heads, be focused always on things that only the “affluent” could relate to or appreciate, or separate ourselves from other brothers/sisters in Christ based on wealth and class.
And we pray:
O Savior, You chose the lowly things of this world, the poor, the downtrodden, the uneducated, the weak, far more than the affluent and wealthy. You did this for Your glory to discourage boasting. Let us all, as Christians, partake of a single Christian “culture” and not divide into our separate groups and neglect to relate to those outside of that group. We are one in You, let us act like it, Amen.
