The Bible teaches us that we are to bring sacrifices to God that are worthy of He who is receiving them. But what can we possibly bring to God that is an acceptable sacrifice; once Jesus paid the price for all of our sins, what can we possibly give God something that is new and fresh and worthy of being received by the Creator of the Universe? Just like the old saying “what do you buy a man that has everything”?
The Psalmist David (Psalms 49:14) as well as the writer of Hebrews (13:15) teach us to bring “sacrifice of Praise”. Praise is the only thing that we can bring to God that He will accept; we give it out of our own volition that is spotless and clean in His Presence. Because it comes from our spirit, it is “pure and undefiled” worship; it is not out of material goods which, technically, we received from Him in the first place.
God the Father wants us to want to worship Him in spirit and in Truth. God created us so that we may have a relationship with Him. Relationship with God is no different than relationship with humans, it requires time, effort and sacrifice. Now sacrifice is not intended to be some sort of self-inflicting pain ritual but rather a willful decision to give of yourself to the other person. What better way to worship God in an undefiled Temple than to offer up sacrifice of praise, which is after all our “reasonable and acceptable service“.
