Apostasy: my thoughts

Apostasy always begins with the heart where a person is turning back which is deliberate and decisive. The heart of apostasy is whether a person was saved in the first place or a Christian was a prodigal. In our hearts, are we in the world or in Christ. Slipping back into unbelief is very highly unlikely since faith begins in the heart which God have given us. Faith is a gift, whether a person actually "recieved" faith as a gift is the question. Anyway... that's just my thoughts. I might be right or I might be wrong. But I will be researching this issue.
