"Do not present an animal with defects because the LORD will not accept it on your behalf." -Leviticus 22:20
The Levitical Laws, more specifically in this case the ceremonial laws, were a foreshadow of what was acceptable worship and what was unacceptable worship. In order for an animal sacrifice to be made, the animal had to have NO blemishes, NO defects, NO sickness. The animal had to be perfect. If there was the slightest flaw or imperfection in the animal being presented, the animal sacrifice would be rejected by God as shown in this verse, "...the LORD will not accept it on your behalf."
As I found myself reflecting on this passage of Scripture this morning, I was reminded of another passage in Romans 12:1(NLT), which states, "And so, dear brothers and sisters, I plead with you to give your bodies to God because of all he has done for you. Let them be a living and holy sacrifice--the kind he will find acceptable. This is truly the way to worship him."
We're told in the Word of God to be perfect as He is perfect, to be holy as He is holy. When we keep that in mind, we will be careful how we live our lives because ALL that we do is worship to God. Our sacrifices must flow out of hearts consecrated, devoted to God.
The LORD will not accept less than the best. We cannot present the sacrifices of our talent, time, praise, effort and the like to the LORD if we are living lives defiled by pretense and hypocrisy. We cannot present ourselves in worship to the LORD if we are half-hearted in our obedience to Him. When our sacrifice to the LORD is blemished and defective, like the animal sacrifice spoken of in Leviticus 22:20, then we will be the kind of sacrifice He rejects.<
