Did God’s people stumble and fall beyond recovery? Of course not! They were disobedient, so God made salvation available to the Gentiles. But he wanted his own people to become jealous and claim it for themselves.
And now you Gentiles have also heard the truth, the Good News that God saves you. And when you believed in Christ, he identified you as his own by giving you the Holy Spirit, whom he promised long ago.
For a time is coming when people will no longer listen to sound and wholesome teaching. They will follow their own desires and will look for teachers who will tell them whatever their itching ears want to hear.
