What determines whether a person goes to Heaven or not is a repentant heart.
Re-pent = return to the highest level. (Where we belong) And God keeps His word even if we don't. If you sincerely want forgiveness, you'll turn away from your sin.
Nice post except for one thing that I somehow noticed.
Your worship of a triune entity is idolatry and your false witness that misleads people into setting aside the commands of God is murder. Your entire religion consists of sinful behavior attractive to only those who love and practice deceit.
As you said, if you turn away from your sins you will be forgiven.
Where there is no repentance there is no forgiveness.
You are not at the highest level, you are at the lowest level.
To understand what I meant by saying 'lowest level' see Genesis 3:14
