" But the authority to interpret God's word doesn't rest with an individual or group. It rests with Christ alone -- all authority is His (Matt. 28:18) as the book is all about Him (Lk. 24:27). And while Christ gives teachers the ability to interpret and teach (Neh. 8:8; 1 Cor. 12:28), or councils wisdom to discern (Matt. 18:15-18), His authority is found in the text alone, and those who interpret it correctly (2 Tim. 2:15). His people will hear the correct interpretation, because the Holy Spirit will guide them into all the truth (Jn. 16:13; 1 Jn. 2:20)."
Baptism is baptism, so long as you believe. It doesn't matter if Judas baptized me. There is no record of anyone baptized that had to be baptized again; it is for believers, and if the pastor proves false, it DOESN'T mean that my baptism, if I believed, was false too.
To the contrary, you are dead and reveal it by refusing to believe that God chose and had mercy on you. Rejecting electing love proves man's depravity, for a few verses down, you see that we are born again, not by human will power or heritage, but by God. You cannot read the book of John and believe free will, unless you chose to stay blind to the Light. The true light of conscience won't save you, but the Light of revelation in the power of the Spirit... so that you actually believe... will.
