The essence of intimacy is to know that we are known. Jesus had just answered the questions the disciples had been discussing among themselves but had not asked Him (Luke 5:22). When they realised that He knew their private conversation, their thoughts, doubts, questions and fears, they wondered - who else could have known other than God? The miracles had not fully convinced them, nor had the wisdom of His teaching; but when He revealed their own deep internal thoughts, they knew that He understood them in an intimate way.
