Matthew25: 31-46, The Judgment of Nations lets people know who will get into Heaven.
Love God above all things & your neighbor as yourself is the commandment.
A belief in Jesus Christ has to be more than talk in the ordinary route to salvation.
The good thief on The Cross praised Jesus, believed in Jesus and had his sins forgiven. (The good-thief suffering death on the cross offered his prayer directly to Jesus Christ.) (The bad thief cursed God and died.)
There are plenty of other of Biblical passages explaining that God is looking doers of the word & just not talkers of the word.
Prior to death, perfect contrition will bring forgiveness of sins.
There is a ‘final exam’ on Judgment Day. The question & the answer is in the Bible.
Q. ‘Do you love me?’
A. ‘Yes Lord, you know I do!’
It’s not possible to deceive God. It’s always pointed-out in regards to the passage cited (Acts15: 31) that there is >more to that passage than simple belief. As beelzebub & his minions believe in Jesus Christ. They couldn’t pass the final exam so they are out of luck.
Where will I go?
