Q. What hinders prayer?
A. A problem in my relationship with God or with others will hinder my prayers.
If I harbor unconfessed sin or live in disobedience, I cannot expect God to bless my prayers (Psalm 66:18-20, Matt 6:12, Psalm 19:12, etc). The same is true if I am not living a life of love for those around me, especially those in covenant with me (ex. 1 Peter 3:7).
