Your heritage doesn't matter to God

“Produce fruit in keeping with repentance. And do not begin to say to yourselves, ‘We have Abraham as our father.’ For I tell you that out of these stones God can raise up children for Abraham.” Luke 3:8
There are many people who think that because their parents are Christians, or their granadparents were Christians, that that automatically makes them Christians. They might be able to trace their family tree back to a well-known preacher or evangelist. It was the same for the Jews who John the Baptist was speaking to here. They prided themselves in the fact that they had descended from Abraham, Isaac, and Jacob. They thought because God had chosen their forefathers and made a covenant with them, that they were automatically God’s people. But as Paul said, “For not all who are descended from Israel are Israel” (Rom. 9:6). That is, not all who are descended from Israel – Jacob, their ancestor – are Israel (which means ‘governed by God’ or ‘prince with God’). Not all Jews are governed by God. We see this even today: most Israelis lead a life as secular as anyone else.
So, saying your parents are Christian or you have a Jewish heritage, counts for nothing. (Conversely, if your parents or grandparents were criminals, it doesn’t disqualify you from becoming a child of God.) What matters is whether our lives are producing the fruit of repentance. Are we seeking to turn from our sin, and do instead the things that please God? Are we thinking the best about people instead of assuming the worst? Are we displaying the fruit of the Spirit in our lives: love, joy, peace, patience, kindness, goodness, faithfulness, gentleness, and self-control? (Gal. 5:22-23).
Having a godly family heritage is a good thing - if you too have found the Lord. Otherwise, it counts for nothing.
