Lev 1-4
I sure am glad that I don't live on the old testament days! All those sacrifices and procedures would be a chore. But they were all a picture of things to come.
Every offering...peace, sin, burnt, meat...one requirement was the same...without blemish. I chuckled to myself as I thought about all the blemished animals. They never had to fear for their life to be taken at the altar. The unblemished animals though were a picture of Christ to come. Only his sacrifice would ben sufficient. Now that I think about it, I'm one of those blemished lambs. It's not that I'm worthless and useless, that's just not my mission. And it's Christ that makes it so that I can live. His perfection took my place.
