The idea that we were somehow once perfect and have strayed from the path ... is misleading.
Not to mention contradictory.
In context [as a tool to assist us precisely in grasping our Purpose - both individually and collectively, even as a PLANET] the allegory of the Prodigal is an excellent beginning point for emphasizing that we are, indeed, PURE and HOLY prior to our descent into Incarnation.
This is not how I see it, nor do we descent into Incarnation.
God causes all those destined from the foundation of the world (Matt. 25:34), to be chosen in Christ, that they should "fall away" (2 Thes. 2:3) from the Truth and "leave their first love" (Rev. 2:4) before they can be truly spiritually converted. Yet this is the plain declaration of Scripture.
Peter fell away:
"Jesus said unto him [Peter], Verily I say unto thee, That this night, before the cock crow, you shall deny me thrice [three times]" (Matt. 26:34).
All the apostles fell away:
"Then said Jesus unto them, ALL YE shall be offended because of Me this night: for it is written, I will smite the shepherd, and the sheep of the flock shall be scattered abroad" (Matt. 26:31).
"And they ALL forsook Him, and fled." (Mark 14:50).
Paul fell away:
"As for Saul [renamed Paul], he made havock of the church…" (Acts 8:3) [while at the very same time he was "blameless" in keeping the Law of Moses] (Phil. 3:6).
ALL the Churches in Asia fell away after being in full support of Paul’s ministry. First:
"The churches of Asia salute [greet] you…" (I Cor. 16:19).
Later near the end of Paul’s ministry:
"This you know, that ALL they which are in Asia be TURNED AWAY FROM ME…" (II Tim. 2:15).
Paul warned the Ephesian Elders about the "flock—church" falling away:
"For I know this, that after my departing shall grievous wolves enter in among you, not sparing the flock [the whole flock]." (Acts 20:29).
Jesus prophesied that all who will become overcomers will have first fallen away temporarily by leaving their first love:
"Nevertheless I have somewhat against you, because you [the seven-in-one golden candlestick church of God that is, was, and will be] have LEFT YOUR FIRST LOVE" (Rev. 2:4).
Jesus Himself calls this leaving of our first love, a falling away:
"Remember therefore from whence you ARE FALLEN, and REPENT…" (Rev. 2:5).
Whenever we "fall," we leave our "first love." For spiritual falling IS, LEAVING LOVE. Jesus said that when we leave our first love we are to ‘remember from whence we are FALLEN…’ Love itself has not failed us, but we have failed love, for true love is not capable of failure or falling:
"Charity [Old English for ‘love’] never fails…" (I Cor. 13:8).
In ALL cases the falling away was caused by man's presumed "Free will".
Man's presumed ability that he HIMSELF ALONE can choose God and follow the path of righteousness.
I believed this once...we ALL did/do.
...Consider the allegory, realize that we are ALL God's Children, that no human being is born inherently sinful ...
"For ALL [all mankind] have sinned, and come [Greek: ‘fall’] short of the glory of God" (Rom. 3:23).
"MANY [not few] will say to Me in that day, Lord, Lord... And then will I profess unto them, I never knew you: depart from Me, ye that work iniquity [margin: ‘lawlessness’]" (Matt. 7:22a & 23).
"But the scripture has concluded ALL UNDER SIN…" (Gal. 3:22).
"But the natural man receives NOT the things of the Spirit of God: for they are foolishness unto him: neither can he know them, because they are SPIRITUALLY DISCERNED" (I Cor. 2:14).
"For the carnal mind is enmity [deep-seated HATRED] AGAINST GOD..." (Rom. 8:7).
It all starts with God, not with us:
"We love Him [God] because He FIRST LOVED US" (I John 4:19).
God made mankind spiritually "naked" (as explained in my previous post).
"Naked"...as in exposed...weak...subject to the lusts and sins of his own heart, so that man will learn that he CANNOT love God first; he cannot obey spiritual laws and commandments; he cannot please God; he cannot accomplish anything of lasting value through his wicked and deceitful heart. (Jer. 17:9). And therefore God's ways will justify His means. The rewards and the blessings are not even to be compared with the glory that God is creating in the human race (Rom. 8:18).
We believe we control our own destiny...we believe we are not subject to higher powers...this is the lawlessness (Matt. 7:23), (II Thes. 2:3) and the beast Revelation talks about.
