This section of text says that there are many more concepts or doctrines regarding Christianity and the Lord Jesus which the apostle wants to speak to this audience but they are not ready for them. They have chosen a path of slow or no growth in their faith which is called sanctification. By the end of the first century this laziness regarding growth in Christ had become so apparent that Jesus told the apostle John to write about this to the Church at Ephesus as part of the book of Revelation. The letters to the churches of Asia in Revelation chapters two and three while focusing on each individual church’s problems were all distributed to all the churches. That is, each of the seven letters went to all the churches. This indicates that the issues were important enough for Jesus to want all of His churches to be aware of the problems that have arisen and to concern themselves them with them lest they fall victim of them as well. This is a major problem today too.
