The Bible says, "God created man after His own image." According to this statement, man possesses two hands because he has a form similar to God's. But this doesn't mean that God is a human being because He has two hands. It is a heinous offence to try to diminish the position of Lord Kṛṣṇa because He appeared in a human form. The truth about His divine potency and supreme position should be learned from the self-realized spiritual master, the saintly souls, and the revealed scriptures.
Demonic persons fail to understand the real purpose of human life. Instead, they are always quick to try to diminish the supreme position of Lord Kṛṣṇa. Such atheists may have very high ambitions and may perform great, noble deeds, but because their ambitions and deeds are cut off from a loving relationship to Lord Kṛṣṇa, the Supreme Godhead, they are all useless. The demon Rāvaṇa wanted to reach heaven by constructing a stairway, but he failed. And all atheists' ambitions are like that.
