HAHAHAHAHAHAHAHAHAHAHA!
So, tell me, can a person accept Christ in his heart as Lord and Saviour, then reject Christ, then accept Him again?
Does the person who has accepted Jesus in his heart as Lord and Saviour retain the free will that God graced him with at birth to commit an act that is of sufficient egregiousness so as to endanger his ultimate union with Jesus? Does Jesus offer forgiveness to such a sinner? ...a resounding "yes" on both counts.
While our Lord wants us to love Him, He ultimately leaves it up to us to do so, because He knows that love not freely given is not love at all.
You have but to read some Christian history to learn that the pervertedly narrow interpretation of Scrpture that resulted in "sola fide" was non-existent until its invention by Martin Luther.
