Mark 8:11-21 ~ The Comprehension of the Disciples

Excerpt:

So, you see, unless the Spirit reveals the truth to them they cannot know. A person cannot understand. Jesus spent three years convincing the disciples that they could not do it. They do not have the faith, they do not have the perception, and they do not have the understanding. It took three years for them to come to a point that they could receive the Holy Spirit and be totally submitted to the Spirit knowing that they could not do anything; it had to be the Lord.
