Mark 4:34 But without a parable spake he not unto them: and when they were alone, he expounded all things to his disciples.
Jesus spent lots of alone time with His disciples. When He was with them He explained what He was preaching and teaching. This is a picture of how we are to teach people.
They hear the messages but need to be able to ask questions and get to understand. Some of the best work we do is not from the pulpit but in the pew. We can discuss the truths. We can help them to understand. That is what Jesus was doing.
Get some people. Spend time alone with them. Teach them the truths of the Word of God.
