It amazes me how the neo-Calvinist mind works. Just look at your words. They do nothing but attempt to avoid the message of Acts 5:31 and do nothing to deal with what it says. All your "it does NOT mean" words smack of incessant denial. Calvinists have this sort of "if I don't understand how this verse fits into my theology then it can't mean what it appears to mean" attitude. Very odd.
How can you be in such denial?
The God of our fathers raised up Jesus, whom you had put to death by hanging Him on a cross. He is the one whom God exalted to His right hand as a Prince and a Savior, to grant repentance to Israel, and remission of sins. (Acts 5:31).
Men of Israel.... Being therefore exalted at the right hand of God, and having received from the Father the promise of the Holy Spirit, he has poured out this which you see and hear....Let all the house of Israel therefore know assuredly that God has made him both Lord and Christ, this Jesus whom you crucified.Now when they heard this they were cut to the heart, and said to Peter and the rest of the apostles, "Brethren, what shall we do?" And Peter said to them, "Repent, and be baptized every one of you in the name of Jesus Christ for the remission of your sins; and you shall receive the gift of the Holy Spirit. For the promise is to you and to your children and to all that are far off, every one whom the Lord our God calls to him.
Repent therefore, and turn again, that your sins may be blotted out, that times of refreshing may come from the presence of the Lord, and that he may send the Christ appointed for you, Jesus, whom heaven must receive until the time for establishing all that God spoke by the mouth of his holy prophets from of old. Moses said, "The Lord God will raise up for you a prophet from your brethren as he raised me up. You shall listen to him in whatever he tells you. And it shall be that every soul that does not listen to that prophet shall be destroyed from the people.' And all the prophets who have spoken, from Samuel and those who came afterwards, also proclaimed these days. You are the sons of the prophets and of the covenant which God gave to your fathers, saying to Abraham, "And in your posterity shall all the families of the earth be blessed.' God, having raised up his servant, sent him to you first, to bless you in turning every one of you from your wickedness.
It is rather plain my friend.
