They had been with Jesus

I need some insight...

the first few chapters of Acts are powerful, and i love peter's preaching!
i am tripped up on something though


Here is some background:
2:38
repent and be baptized every one of you in the name of Jesus Christ for the forgiveness of your sins, and you will receive the gift of the Holy Spirit

2:43
and awe came upon every soul, and many wonders and signs were being done through the apostles


after the lame man gets healed through peter's faith in Jesus and they are arrested and before the council, the council has this to say:
3:13
now when they saw the boldness of peter and john, and perceived that they were uneducated, common men, they were astonished. and they recognized that they had been with Jesus.

acts 4:29-31
And now, Lord, look upon their threats and grant to your servants to continue to speak your word with all boldness, while you stretch out your hand to heal, and signs and wonders are performed through the name of your holy servant Jesus.” And when they had prayed, the place in which they were gathered together was shaken, and they were all filled with the Holy Spirit and continued to speak the word of God with boldness.

5:12-13
now many signs and wonders were regularly done among the people by the hands of the apostles. and they were all together in solomon's portico. none of the rest dared join them, but the people held them in high esteem.




why would that be? why would the apostles be the only ones walking in the power and boldness of the Holy Spirit? The others were also filled with the Holy Spirit. All I have seen so far in healings and miracles are by the faith of the apostles.

thoughts??
