What kind of power will those who share in the first resurrection have?

The Holy Spirit speaking through the pen of apostle John said those who share in the first resurrection will have power while those who share in the second resurrection will not have any kind of power but will be priests and prophets for the Most High. >Blessed and holy is he that hath part in the first resurrection: on such the second death hath no power, but they shall be priests of God and of Christ, and shall reign with Him a thousand years. I understand the Spirit is urging believers to do their best to be part of the first resurrection but what kind of power will God give those who partake in the first resurrection?
