Believers should continually ask God to purify their mind and keep it fresh. We should ask God to wash out all our bad thoughts and vain imaginations toward God so that what we believe will be fully in accordance with the eternal will of God. We should ask God not only to make us think about Him, but also to make us think about Him in the right way. We should ask God not to let any thought issue from our evil nature. If there is any such thought, we should ask that God’s light shine upon it and terminate it immediately.
