Heaven is such that all who have lived well, of whatever religion, have a place there.
Conscience is God's presence in humans.
Love is the life of humanity.
Man knows that there is love, but he does not know what love is.
The nature of heaven is to provide a place there for all who lead good lives, no matter what their religion may be.
If love is not married to wisdom (or if goodness is not married to truth), it cannot accomplish anything.
