You cannot pray without the Holy Spirit helping you. Also, you must pray IN THE NAME OF JESUS, otherwise your prayer invalid. It is almost like saying in your own power. You cannot just say the LORD, yes you can say after you have said the LORD JESUS. Remember there are many Lords, lord of the flies, earthly lord and so on. You must pray in the name of our Lord Jesus. Plead the Blood of Jesus and always cover yourself by the Blood for protection. Also, you must walk with God everyday. Example, you cannot pray - Lord..... and watch the porn later. I am speaking to someone here. God bless.
