NO - It is not okay to be angry with God
Over the last decade or so I have heard it said many times that it is okay to be angry with God. Anger is a "strong feeling of annoyance, displeasure, or hostility." The problem is that God never does anything to deserve your anger, which means that whenever you are angry with God you are sinning. Although, many people use the Psalms to defend their position, it does not support their perspective. Let's look at one.
How long, O Lord? Will you forget me forever? How long will you hide you face from me? How long must I take counsel in my soul and have sorrow in my heart all the day? How long shall my enemy be exalted over me? (Ps. 13:1-2)These verses are not displaying displeasure or hostility or anger in any common meaning of the word, rather they are a cry for understanding and longing for God. This only is confirmed in the verses that follow:
Consider and answer me, O Lord my God; light up my eyes, lest I sleep the sleep of death, lest my enemy say, "I have prevailed over him," lest my foes rejoice because I am shaken. But I have trusted in your love; my heart shall rejoice in your salvation. I will sing to the Lord, because he has dealt bountifully with me. (Ps. 13:3-6)The Psalmist is confirming their trust in God and the joy and grace which He gives. Undoubtedly there are times when we do not understand what is happening and wonder where God is in the situation, but we should never get angry at him. Instead, we should trust Him even more knowing that He loves us.
