Mark 12:27
Jesus is very clear here. The Sadducees were totally incorrect, and he told them so. He was not afraid to tell them how wrong they were.
This is really quite an interesting interchange because this question was not as dangerous as many of the others which Jesus was asked. The Pharisees would agree with him about the reality of the resurrection. However, it is very unlikely that they ever thought of his solution to the problem.
Heavenly Father, you are the Holy God of all. Life itself is in your hands. And, we know that we live only because that is your will. Life is up to you. You own it and maintain it. Thank you for giving us life here, and in the world to come! In the name of the Lord Jesus Christ I pray and praise you, Amen.
