Its to bad you cant find that stated in the bible...

on the day of pentecost you erronously add your faulty interpretation, peter did not say that God desires all mankind to repent, in fact, peter taught a limited particular atonement, for peter did not even understand when he preached this sermon that the gentiles too were a chosen people of God..He came to that understanding in acts 10..

So you show your ignorance of scripture here in bringing up acts 2.

He peter was addressing the house of Israel

acts 2:

Therefore let all the house of Israel know assuredly, that God hath made the same Jesus, whom ye have crucified, both Lord and Christ.

The repentance was from the partaking of putting to death the Lord Jesus christ,,

acts 2:

23Him, being delivered by the determinate counsel and foreknowledge of God, ye have taken, and by wicked hands have crucified and slain:

Peter seen already they had been granted the gift of repentance, he just further instructed them..

37Now when they heard this, they were pricked in their heart, and said unto Peter and to the rest of the apostles, Men and brethren, what shall we do?

peter knew that these men were convicted by the holy ghost as jesus promised he would do to the elect church..jn 16:

7Nevertheless 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.

8And when he is come, he will reprove the world of sin, and of righteousness, and of judgment:

9Of sin, because they believe not on me;

he convicted those jews there on pentecost because of their past unbelief and putting him to death. That also means that the elect are delivered from unbelief by the mighty working of the spirit of God..

peter also clearly designated that this salvation is toward only a called people, not all mankind like you so falsely impose with your false teaching..

acts 2:

39For the promise is unto you, and to your children, and to all that are afar off, even as many as the LORD our God shall call.

so dont try and run to peter on acts 2 to help promote your lies..

repentance is a gift to a chosen people from their saviour..

acts 5:

31Him hath God exalted with his right hand to be a Prince and a Saviour, for to give repentance to Israel, and forgiveness of sins.
