First, the fire for the burning of the incense was to be taken only from the bronze altar of sacrifice, not any fire was to be used (Lev 16:12-13). The sacrifice points to the cross of Christ which is our altar and the only sacrifice for sins that is needed. And so our prayer must always be in the name of Jesus, it must be based on the sacrifice of Christ. A true prayer is not about powerful or beautiful words, but one that exalts the works of Christ. What an amazing blessing we have, that God gave us a way to pray and have communion with him! For how is it that the holy God should hear the prayer of sinners, and yet he hears us when we come to him through Christ. Secondly, the incense was a mixture of specific spices (Ex 30:34-38), not any kind of blend would do. And so our prayer must not be a senseless babbling, but it should follow the pattern of the Lord’s prayer that Jesus gave to his disciples. We must receive the Spirit who helps us in our weakness and who leads us in a prayer that is according to the will of God (Rom 8:26).
Lastly, the prayer was to be seasoned with salt (Ex 30:35) which was a symbol of purity and holiness, and also God’s covenant (Lev 2:13). And once a year, on the day of Atonement, the priest would cleanse the altar of the burned offering with the blood of the atoning sin offering (Ex 30:10). And so we must remember that we are in a holy covenant with God, through the blood of the Lamb, and offer prayer that is pure and holy. We must repent and be renewed first, for how can God receive a prayer from a sinful and unrepentant heart? And so we see, that the making of the tabernacle was not about making furniture but a pattern of life that taught God’s people how to properly approach him, receive his grace and live a life that is a living pleasing sacrifice to God. And we will do well to learn and follow the pattern shown to us in Christ as well.
