The beloved disciple John, when in the Spirit, saw golden vials in the hands of the worshipers of the Lamb around the throne. These golden vials, he says, were "full of odors, which are the prayers of the saints" (Rev. 5: 8). Are you, dear reader, every day filling golden vials around God's throne with the sweet odor of prayer? Again, this disciple, when the seventh seal was opened, saw seven angels standing before God with seven trumpets. Then came another angel, with a golden censer. To him was given incense, which he offered with the prayers of saints upon the golden altar, and the smoke of the incense which came with the prayers of saints ascended before God. (See Rev. 8:3, 4.) We have the privilege of mingling our prayers with the incense that is being offered before the throne. The Psalmist seemed to comprehend something of the nature of prayer when he said, "Let my prayer be set forth before thee as incense, and the lifting up of my hands as the evening sacrifice." Psa. 141:2. The prayers that were offered by the devout Cornelius were so fragrant before God that they were kept as a memorial of him. A memorial is something kept in remembrance of any one. If you want to be kept in remembrance before God, see that your prayers are highly impregnated with a sweet odor. You must pray or die. No one can retain spiritual life any great length of time without prayer. So we exhort you to a life of prayer. SHUT THE DOOR. It is as impossible to live and prosper spiritually without prayer as it is to live and prosper physically without food. Those who enjoy a close walk with God and have power with him are those who pray. Natural abilities and intellectuality can never supply any lack in spirituality. Unless you are spiritual, you are of but little use to God; and to be spiritual, you must live much in prayer. It is not those who are on their knees the oftenest or the longest that do the most praying. Some may pray more real prayer in one hour than others in two or three hours. Too many people leave the door open. Prayer that feeds the soul must be offered with the door shut. "But thou, when thou prayest, enter into thy closet, and when thou hast shut thy door, pray to thy Father which is in secret." Matt. 6:6. God is in secret. He is hidden from the world. The world does not see him, neither knows him. You can never reach God in your prayers unless you shut out the world. Shutting the door means something more than closing the door of your literal closet. Persons may enter the literal closet and close the door, and yet have the world in their hearts and thoughts. Such have not closed the door in the true sense.
