Would you agree that even if a person did "fall away" as you suggest they could still be called back by God?
No. I think the Bible is clear on the issue that, by definition, "falling away" is a permanent choice by the one who does - "...it is impossible to renew them [who have fallen away] again to repentance, since they again crucify to themselves the Son of God, and put Him to open shame" (Heb 6:6). It seems clear God cannot call, or renew such a one as this back.
However, what I think you are referring to is what I labeled "fallen back" (which is just my own phrase). I too know Christians who have fallen back into sin and stepped away from the Lord for a period, and then have been convicted of their sin, confessed it, repented and sought (and received) forgiveness for it.
We have
all "fallen back" at times in our Christian walk, sometimes for a moment, sometimes for days, weeks, months, I don't know - even years perhaps. Anytime we sin, and for the duration of the sin, we are "fallen back."
And it is God's kindness that leads us back to repentance. And all Christians have, do, and will again sin and need His kindness once again. Such is life on this earth and in these bodies.
Fortunately, Christ's death, burial, and resurrection has released us from the power of sin, that we needn't obey its lusts any more. And we are urged to stand firm against temptations to sin - but the reality now is that we still do sin, hopefully less and less as we mature in Christ, but nevertheless, we do sin and we have an advocate in Jesus when we do. Amen!
But "falling away" is different than "falling back" (again, just my phrase). Falling away is so serious as to be eternal, permanent, without hope of renewal. God can call back the latter, but not the former - any more than He can call any
unrepentant unbeliever to Him, for such have made God their enemy and they express their enmity for Him in their wanton sin. Moreover, what makes the "fallen away" so hopeless is that they once tasted God's kindness, but turned their back on it, and Him - much like Judas perhaps.
So it is very important to understand the distinction.
I hope I made myself clear??? Please, if you question this at all or have trouble with what I've said, let me know and we can discuss it further, ok?
