Do you want your prayers answered? If so, you must be in right standing with the Lord.
“For the eyes of the Lord are on the righteous and his ears are attentive to their prayer, but the face of the Lord is against those who do evil.” 1 Peter 3:12
The word evil used in this verse is kakos, which means of a bad nature, not as it ought to be.
So often, we have resurrected something in our lives that holds God back from answering our prayers, unforgiveness, strongholds, and ungodly beliefs. Ask the Lord to show you if something in you is not in right standing with Him.
