Peter did not try to convince the Jews of the deity of Jesus based only upon the miracles that He performed. He reminded them of the “miracles, wonders and signs” that Jesus had performed in the open and that were known of by the Jews themselves (vs. 22), but that was not the extent of Peter’s reasoning.
While Peter affirmed that the apostles had indeed seen the risen Savior, and while he reminded the Jews of the abundance of miracles that Jesus had performed during His public ministry, demonstrating the power and authority of God behind what He taught, probably Peter’s strongest appeal was based on scripture.

We can believe in Jesus because He fulfilled the scriptures that prophesied of Him!
When it comes to what we believe and teach and practice as Christians, our source for determining the truth is scripture. God has communicated His will to us through His word. We teach what we teach as to salvation because that is what scripture teaches about salvation. We worship the way we worship because that is how we are taught in scripture to worship. We strive to maintain the structure of the church that we do because that is the structure taught in scripture. We believe what we believe as to eternity, Heaven and Hell because that is what is revealed on those subjects in scripture.
Too many people do not think carefully enough as to why they believe what they believe. Too many do not give enough consideration as to how they are living their lives as compared to how the Bible teaches us to live. Too many people give too much emphasis as to how they feel about something rather than as to what God’s word says. When we live by the teachings of God’s word, rightly applied, we know we are right. In this day and age of such skepticism in regards to truth, we can be assured that we are living in the truth if we live by the teachings of the Bible. God’s word is our guide book, our source for truth…
