Matthew 7:21 is not refering to those who are Born Again.
John 6:39New International Version (NIV)
39 And this is the will of him who sent me, that I shall lose none of all those he has given me, but raise them up at the last day.
The Bible says that he that endures to the end shall be saved. Again we can still walk away from Gods grace. Consider Matt.13 the parable if the sower...
20 The seed falling on rocky ground refers to someone who hears the word and at once receives it with joy.21 But since they have no root, they last only a short time. When trouble or persecution comes because of the word, they quickly fall away.
He fell away when persecution came. You have to first be saved to fall away.
John 6:39New International Version (NIV)

He fell away when persecution came. You have to first be saved to fall away.
There is only one person in that parable that is truly born again, and its not the one you say is and the walks away. many deceive themselves. and never where part of the invisible church.
The visible church has the wheat and the tares..the tares fall away and never where.. the invisible church are those who truly are in Christ.
Remember Jesus said:
