The New Testament is painstakingly clear that the order of nature does not determine the order of grace. "But God chose what is foolish in the world to shame the wise; God chose what is weak in the world to shame the strong; God chose what is low and despised in the world, even things that are not, to bring to nothing things that are, so that no human being might boast in the presence of God" (1 Corinthians 1:27-29). Tradition does not determine grace. Convention does not dictate grace. Neither does giftedness or natural endowments. Grace does not bow to social privilege or status Genesis 25:19
In Genesis 25, we see this principle again at work with Esau giving up his birth right to his younger brother Jacob for a bowl of stew! The last will be first and the first will be last. Join me in reading Genesis 25 and be encouraged!
