Your spiritual growth is measured by how much of the life of Christ you have flowing through you and working in you and not by how long you have been a Christian. It's possible to be ten years in the faith and still be a spiritual babe. Spiritual babes never have their character changed by the word of God because they do not dwell in the Word for long enough. They may have a mental understanding of the Word and might even think they are God's special gift to the Church, but their lack of maturity causes more problems than solutions. They go around thinking every other Christian is carnal.
Spiritual babes have an over exaggerated opinion of themselves and often show it.
They never get on in Church and are often seen floating from church to church. As you read God's Word certain parts of it will minister to you more than others. Study the parts that minister to you the most. Study of God's Word should be fun and interesting. You are getting to know more about the almighty God.
