Ok from what I've read so far, I understand that according to the Sikhi's the soul merges into God. Am I right so far?
I also read that the person's soul only enters God when it is pure.
Moreover, we all know that human beings have faults, be it emotional, physical, psychological any kind of fault, but humans are faulty in general. Although we strive for excellence in front of god, we are still faulty and we commit sins.
What we don't know is the time of our death.
You and I know that no person can be sinless at any point in time. Sometimes we commit sins purposely and sometimes unconsciously, so if we die right now while still having sins, how will be 'Merge' with god?
Sorry if I have said anything offensive.
