Wilson's Dictionary of Bible Types [1]

 Psalm 1:1 (b) This word has the same meaning in every place where it is used. The prefix "un" means to be without. Joined to the word "godly," it means that the person, the nation or the subject under consideration is with out GOD. The ungodly person may be beautiful in character, attractive in manner, cultivated, refined and educated, but he is living without GOD. He has no faith in GOD, and may be rebellious toward GOD. He may be quite religious in his outward actions, and yet have no knowledge personally of Jesus Christ Such a person is un-godly.

International Standard Bible Encyclopedia [4]

un - god´li ( רשׁע , rāshā‛ (  Psalm 1:1 ), "wicked," בּליּעל , belı̄ya‛al ( 2 Samuel 22:5 ), "worthless"; in the New Testament ἀσεβής , asebḗs ( Romans 5:6 ), e.g. indicating that the persons so called are both irreverent and impious): Trench says that the idea of active opposition to religion is involved in the word, that it is a deliberate withholding from God of His dues of prayer and of service; a standing, so to speak, in battle array against God and His claims to respect, reverence and obedience. Those whose sins are particularly aggravating and deserving of God's wrath are the "ungodly." And yet it is for such that Jesus Christ died ( Romans 5:6 ).
