Strangely enough, I think I'm more Calvinist in this area than you.
First, if you truly believe that, you cannot be a Calvinist, since Calvinism vehemously defends God's right to show all the partiality that He wants, even in the matter of choosing whether to allow us to love Him or not.
Secondly, I do believe that the gifts of the Spirit are still operative today. Nevertheless, 1 Cor. 12-14 is clear that God does not give all believers all the same gifts. Ergo, there's a measure of "partiality" involved there--that is, He equips us for the unique ministries He has in mind for each of us, but not everyone ministers in the same way. How many people go around parting the seas, for example?
The only Spiritual gift that God promises to give abundantly to anyone who asks is wisdom, per James 1:5. Now, I do believe that if you are fruitful with your given gifts, you will be given more (and more responsibilities to go with them), but when and how much is strictly up to God.
That being said, jkl1122 is incorrect on how many were immersed (baptized) in the Holy Spirit in Acts. There are other instances where the Holy Spirit fell upon people with power when the Apostles laid their hands on them. The Apostles came to Philip's evangelistic meetings expressly to give the Spirit's full immersion to those who had been saved, for example (remember how Simon the Sorceror wanted to buy that power), and the fact that the Gentiles were exhibiting the Spritual gifts was a major part of Paul and Barnabbas' case in Acts 15. Besides, 1 Cor. 12-14 makes no sense except in the context of continuing miracles by the Holy Spirit in the Church, including the gift of tongues.
I will be the first to admit there are probably other instances of Holy Spirit "baptism" in the New Testament. However, this is not where salvation takes place.
No, you either do not understand the definition of "partiality" or Calvinism. Partiality means "a predisposition to like something". God in His holiness is not predisposed to like any of us. He does not select us based upon whether we have blue eyes or freckles. God rich in His mercy and love saves us by His divine grace according to His own counsel to carry out His will. That is not partiality.
I hate analogies but let me give an example anyway. If I needed tires for the car and said I’ll only buy Goodyear because they make a great tire I would be partial to Goodyear tires. Other dealers could rightfully accuse me of being partial to Goodyear tires and I certainly couldn’t argue with them. On the other hand if I said I needed four tires to get the car running and just happen to drive pass a Goodyear Tire store and purchase tires, then the other tire dealers can’t complain I was “unfair” to them.
"Secondly, I do believe that the gifts of the Spirit are still operative today. Ergo, there's a measure of "partiality" involved there--that is, He equips us for the unique ministries "
“For there is no partiality with God.” Romans 2:11 see also Gal 2:6, Eph 6:9, Job 34:19
I know some Calvinists (and Arminians) would disagree but I'm believe all the gifts are still operative today as well. However, God gives faith, talents and gifts out as He sees fit and in the measure He determines so we may accomplish His purpose. Some people bear fruit 100 fold, some 60, some 30 but it’s all according to God plan. Some are great evangelists while others are simply meant to comfort a dying person. We are vessels chosen for a specific purpose. There is no partiality because He has a different plan for each of us and He will provide us what we need to accomplish that plan.
There is a Biblical example of this.
”Now this He said, signifying by what kind of death he [Peter] would glorify God. And when He had spoken this, He said to him, “Follow Me!”…So Peter seeing him [John] said to Jesus, “Lord, and what about this man?” Jesus said to him, “If I want him to remain until I come, what is that to you? You follow Me!”” John 21:19-23
God gave a different mission to Peter than John just as He gives each of us our own assignment. We know from scripture and history Peter was a great evangelist and leader of the early church. John on the other hand wrote some of the greatest scriptures in the Bible. Both had their influences but in different ways. It is not our place to question our assignments any more than it was Peter’s place to question John’s assignment. Our Lord Jesus showed no more partiality for Peter than He did for John or vice versa with the gifts and talents He gave each.
For God to utilize His People in different ways is not partiality. To use me in a different manner than He uses you is showing no partiality to either one of us. He uses each of us to further His Plan. Each of us have different functions, different gifts, and different paths to follow, as He Wills. There is no pariaility in that.
An acusation of partiality in such things is actually the sin of jealousy on the part of the person accusing God of such, even hypothetically. And to make such an accusation against a Believer with whom you disagree doctrinally as a means of maligning his doctrine is being less than truthful. It is a false accusation, because as a Christian, you CAN'T believe such a thing of God and yet love Him. Therefore, you accuse another falsely of something that is within your own heart, and you are actually in a veiled way questioning his salvation.
Who are you that judges another's servant? To his own master he stands or falls. But he will stand, for God is able to make him stand. (Rom 14:4)
