There is darkness and light in the universe, the darkness is trying to cover the universe, and the light is trying to uncover it. In a similar way, the followers of all religions are trying to spread their beliefs and thinking they are the light and others are darkness.
So, who is right? Well, those who can describe God are in the light and those who cannot are in darkness.
Who is God? One who has proved Himself to be eternal by appearing millions of times. Only Lord Krishna has proved Himself to be eternal, because He has appearing millions of times.
Who is most loving and most merciful? One who does not advocate slavery, rape, stoning, looting, intolerance, eternal punishment… Only Lord Krishna never advocated these evil ideologies.
Who is most forgiving? One who gives unlimited chances (reincarnation) and not just one. Only Lord Krishna gives us unlimited lives and thus unlimited chances.
Who is most just? One who ensures justice for all living beings. Lord Krishna ensures justice for all living beings via the law of nature, karma.
“My dear King Yudhiṣṭhira, the brāhmaṇas, especially those engaged in preaching the glories of the Lord throughout the entire world, are recognized and worshiped by the Supreme Personality of Godhead, who is the heart and soul of all creation. The brāhmaṇas, by their preaching, sanctify the three worlds with the dust of their lotus feet, and thus they are worshipable even for Kṛṣṇa.” (Shrimad-Bhagavatam 7.14.42)
