In Psalm 109 David is basically venting to God. He is frustrated with the liars and slanderers. David pleads with God to live up to His name (according to His character) in Psalm 109:21, But you, O Sovereign Lord, deal well with me for your name’s sake; out of the goodness of your love, deliver me. Believe it or not, God is ok with our venting. He is not hurt or offended when we have had enough of the twisting and spinning justifications of this lost world. When we plead for God to act, He hears us. He will act according to His will, which means it may not be in our timing, but God does not ignore our pleas. Trust in Him and have faith in His perfect plan!
