What does the Bible say about the importance of hearing the law?

Proverbs 28:9 states, 'He that turneth away his ear from hearing the law, even his prayer shall be abomination.' This verse emphasizes the imperative nature of hearing God's word. The Scriptures repeatedly command both believers and non-believers to listen to the Lord's word. The act of refusing to hear God's law results in grave consequences; it demonstrates a heart turned away from God. Not only does this refusal manifest in one's spiritual state, but it also sullies one's prayers, rendering them ineffective and offensive in God's sight.
