I'm not trying to be argumentative. Please don't take it that way. I lost a life long friend over this topic a few years ago. We have discussed the Scriptures with one another for so long. I would sit and listen to him for hours at a time. He was somewhat a mentor to me. I don't want to offend anyone over this topic. However, I do believe you see the Scriptures differently if you accept what I'm saying. Up to you.
1. Regeneration is not a complete removal of sin. It is not removal of the flesh. Nor is it the removal from being around sin. It is a new "birth".
Abraham was circumcised in heart. Which is the new birth. Circumcision was conducted for Hebrew boy on the 8th day. A sign of a "new creation/creature". This why Paul appeals to the circumcision of the heart.
Rom 2:29 But he is a Jew, which is one inwardly; and circumcision is that of the heart, in the spirit, and not in the letter; whose praise is not of men, but of God.
2. Example of the Eternal abiding Spirit with those who have experienced the new birth.
Psa 139:7 Whither shall I go from thy spirit? or whither shall I flee from thy presence?
Psa 139:8 If I ascend up into heaven, thou art there: if I make my bed in hell, behold, thou art there.
Psa 139:9 If I take the wings of the morning, and dwell in the uttermost parts of the sea;
Psa 139:10 Even there shall thy hand lead me, and thy right hand shall hold me.
David had most certainly known sin BEFORE Psalm 139. He had experienced the unwavering presence of God with him.
Jeremiah couldn't live without it.
Jer 10:23 O LORD, I know that the way of man is not in himself: it is not in man that walketh to direct his steps.
Psa 37:23 The steps of a good man are ordered by the LORD: and he delighteth in his way.
Psa 37:24 Though he fall, he shall not be utterly cast down: for the LORD upholdeth him with his hand.
3. The misunderstanding of the "gift of the Holy Spirit".
Joh 16:7 Nevertheless I tell you the truth; It is expedient for you that I go away: for if I go not away, the Comforter will not come unto you; but if I depart, I will send him unto you.
This not because the Spirit of God had not be gifted in the new birth before this time. It was because the Spirit of God was with Christ from His baptism forward.
Luk 3:22 And the Holy Ghost descended in a bodily shape like a dove upon him, and a voice came from heaven, which said, Thou art my beloved Son; in thee I am well pleased.
4. The disciples were simply "clean" through the words of Christ. THEY...... had not yet received the Spirit of God. This is not an indication that no one ("up that time in history") did not receive the abiding Spirit of God in the new birth.
Joh 15:3 Now ye are clean through the word which I have spoken unto you.
Mat 9:6 But that ye may know that the Son of man hath power on earth to forgive sins, (then saith he to the sick of the palsy,) Arise, take up thy bed, and go unto thine house.
There is much more but I'm stop there. Tell me where I'm wrong. I'll listen...
