Faith's Checkbook (By: C.H. Spurgeon)

                                                             What Sanctifies Our Offerings?

The priest shall put some of the blood on the horns of the altar of sweet incense before the Lord.
                                                                                       ~  Leviticus 4:7

  "The altar of incense is where saints present their prayers and praises, and it is delightful to think it is sprinkled with the blood of the Great Sacrifice. This is what makes our worship acceptable with Jehovah: He sees the blood of His Son, and therefore accepts our homage.
  Sin mingles even with our holy things; and our best repentance, faith, prayer, and thanksgiving could not be received of God were it not for the atoning sacrifice. "The blood" is the foundation of comfort and hope. It gives strength to prayer. It is "before the Lord," and therefore it ought to be before us. It is there to sanctify our offerings and gifts.
  So let us pray with confidence, since the Victim is offered, the merit has been pleaded, the blood is within the veil, and the prayers of believers must be sweet unto the Lord." (By: Charles H. Spurgeon ~ One Minute Devotions)
