I can hear you saying, "the sects are from God". But, maybe the ones who lead those sects know that rule.Peace, truth, kindness, justice, love, forgiverness, goodness, oneness is virtues from God. It is divine virtues.
And sects within a spesific religion has different degrees of divine virtues. The different religious sects has different degrees of God's truth in it.
So the religious sects who teach most about those divine virtues like peace, truth, kindness, justice, love, forgiverness, goodness and who do not teach hate and violence is really from God.
