We had a visiting preacher come through our church a while back. Awesome preacher, but honestly cant remember what he preached about although I'm sure it was good. I do however remember well a little nugget he just briefly talked about before he started his message.
He said that in the Old Testament the person who brought sacrificial offerings to be burned before the Lord were not scrutinized or inspected, the actual animal was. The animal had to be clean, without blemish, young, spotless. The person who actually presented the offering to the Lord only need have faith and obedience. Brings tears to my eyes just writing that!! Makes me so thankful! Jesus Christ is our sacrifice. All we have to do is believe and obey!!
1Peter 2:5 you yourselves, as living stones, are built up as a spiritual house to be a holy priesthood and to offer spiritual sacrifices that are acceptable to God through Jesus Christ.
