Sikhism’s Worldview of the Human Problem:

Sikhism doesn’t understand that sin has separated us from the true God and that there is no way, other than through the salvation that God has provided through Jesus, that we can be reconciled to God.

Because Sikhism misses the real god, they cannot really understand the real problem, sin.  Sikhism does teach that sin is the problem and that being separated from their god called Sat Guru.
