Snup,
your question is a little odd cos heart is actually spirit except that heart has one extra component -- will. so if one's spirit is already redeemed, the heart cannot be closed.
I believe you mean the SOUL -- mind, will, emotions -- being closed to God ie not obedient to the Word.
When we are born again, the spirit in us (which is the real you and I) was recreated/born of God.
But the soul (mind, will, emotions) as well as the body/flesh are not redeemed yet. That's why the Bible says the Word of God "saves our soul", and to renew our minds with the Word, line up our emotions/will with the Word. Subject the desires of the body under the promptings/leading of our spirit which is led by the Holy Spirit. these things we have to do ourselves by the grace of God.
point: a Christian who does not do these things (we are all guilty to some degree) will get into all sorts of problems in this life, but in the end he is still saved by the grace of God becos his spirit is already recreated.
