Are you sure of your reference? I just re-read Galatians 3 and find nothing to support this sprinkling of outpoured Spirit...
Ok call it an outpouring instead of a sprinkling. But holiness is passive, so a
full outpouring would make me instantly as holy as Christ is now. That's why I prefer to call it a light sprinkling.
In any case, I likely won't tarry here much longer (I've got work to do), but I'd like to briefly show you what Andrew Murray saw in chapter 3 of Galatians. To summarize:
(1) I received the Holy Spirit for regeneration. That was an influx of holiness
(2) Therefore, growing in holiness MUST be a matter of
receiving more of such outpourings.
Point #2 is one of the main points of Galatians 3. (There's a LOT of good stuff in that chapter but I can't cover it all here). Verses 1 and 2:
"O foolish Galatians! Who has bewitched you?...Did you
receive the Spirit by works of the law, or by hearing with faith?"
Already Paul is hinting that sanctification isn't
achieved by obeying the Bible but
received as an outpouring. Same thing in the next verse - the only Bible the Galatians had was the Law, and Paul says sanctification is NOT advanced by observing the Law.
"
3Are ye so foolish? having
begun in the Spirit, are ye now made perfect by the flesh?...He therefore that supplies to you the Spirit, and worketh miracles among you, does He do it by the works of the law, or by the hearing of faith?"
How had they begun? By
receiving an outpouring. The Galatians need to proceed in the same way begun - they need to receive more outpourings. Gordon Fee wrote:
“The clear implication is that even though [the Galatians] have already received the Spirit, there is another sense in which God ‘supplies’ the Spirit again and again” (Gordon Fee,
God’s Empowering Presence (Peabody: Hendrickson Publishers, 1994), p. 388).
Paul refers to it as receiving the Spirit by the hearing of faith. The REASON for this is a metaphysics hinted at Isaiah 55:11 (which I cannot detail and defend here) - an outpouring of the Spirit is actually the SPOKEN divine Word of God's mouth. Thus to receive the Spirit is ALSO to hear the voice of the Lord. The two go hand in hand.
Verse 5 again:
"He therefore that supplies to you the Spirit, and worketh miracles among you, does He do it by the works of the law, or by the hearing of faith?"
Now here's the clincher. To the Galatians, Paul wants to PROVE his doctrine of sanctification by appealing to Abraham. In the VERY NEXT VERSE, he appeals to Abraham's justification by faith at Gen 15. Yet Abraham was already justified by faith prior to this point! This raises two questions:
(1) How could Abraham be justified twice?
(2) What has justification got to do with the discussion of the Galatians becoming mature/sanctified?
Again, the heart is volumetric. Faith
proper (faith as the fruit of the Spirit as opposed to ordinary self-generated human faith) exists only in those parts of the heart privy to an outpouring. As yet, the rest of the heart is NOT justified by faith (to be technically precise). Thus we can describe sanctification as a series of justifications (outpourings). (Gordon Fee acknowledged that the Galatian epistle mostly has in mind sanctification when it uses the term justification).
Again, verse 6 adduced Abraham's example as proof that justification/sanctification/maturation is a matter of receiving the Holy Spirit again and again, by the hearing of faith. (Such an outpouring is the spoken divine Word per Isaiah 55:11). Let's turn back the pages, to Paul's reference:
"After this, the [divine]
word of the Lord came to Abram in a vision [speaking promises]
6Abram believed the Lord, and he credited it to him as righteousness." (Gen 15).
This proves Paul's point. Through the hearing of faith (see Rom 10:17), Abraham received an outpouring of the divine Word as a justification by faith. But he was already saved by faith, so this outpouring
MUST have been a sanctification. Paul also mentioned miracles received by the hearing of faith. Did Abraham get any miracles? Yes: the promise of a child in his old age, for example.
