Pope Shenouda III
The acceptable prayer is the one that comes from a pure heart.
The Bible says, “The sacrifice of the wicked is an abomination to the Lord, But the prayer of the upright is His delight” (Prov 15:8) and (Prov 21:27). God has rejected the prayer of the evil men and said to them, “When you spread out your hands, I will hide My eyes from You; Even though you make many prayers, I will not hear. Your hands are full of blood” (Is 1:15). On the other hand, the Bible says, “The effective, fervent prayer of a righteous man avails much” (Jas 5:16)..
