Why do you not believe God's Words??
Romans: Chapter 10 verse 9-10-13
GOD SAYS=
That if thou shalt confess with thy mouth the Lord Jesus,
and shalt believe in your heart that God hath raised him
from the dead, thou shalt be Saved. For with the heart man
believeth unto righteousness; and with the mouth confession
is made unto Salvation. For whosoever shall call upon the
name of the Lord shall be Saved........
Why don't you believe Jesus words:
He who believes and is baptized will be saved (Mk 16:16)
Peter wrote: Baptism, which corresponds to this, now saves you (1Pet 3:21)
