“Not all those who say ‘You are our Lord’ will enter the kingdom of heaven. The only people who will enter the kingdom of heaven are those who do what my Father in heaven wants.
You must do this not only while they are watching you, to please them. With all your heart you must do what God wants as people who are obeying Christ.
But the truly happy people are those who carefully study God’s perfect law that makes people free, and they continue to study it. They do not forget what they heard, but they obey what God’s teaching says. Those who do this will be made happy.
