Romans 10:9
that if you confess with your mouth Jesus as Lord, and believe in your heart that God raised Him from the dead, you will be saved;
2 Corinthians 5:17
Therefore if anyone is in Christ, he is a new creature; the old things passed away; behold, new things have come.
1 Peter 1:23
for you have been born again not of seed which is perishable but imperishable, that is, through the living and enduring word of God.
It is not up to me to decide what is in an individual's heart. One, according to the above scripture, is born again, saved if they confess and believe in our Lord Jesus Christ as their savior.
