That is, it is not the children of the flesh who are children of God, but the children of the promise are regarded as descendants (Romans 9:8).
But I have good news. There is a family that lasts forever. It begins here on earth and is only realized in perfection after we die. When a person decides to become a follower of Christ, he or she enters a giant family of faith—the church.
Now, there’s no perfect church. If you find one, please don’t join it; you’ll mess it up in a skinny second because we’re all sinners who fall short of God’s best. But in the family of faith, we’re forgiven sinners who begin a process of being transformed into the people God wants us to be. Looking for a family that lasts? Know Jesus and enter into the only family that lasts forever.
