“concerning sin, because they do not believe in Me;” (John 16:9)

Jesus redefined sin. It had been breaking the Law of Mosses. Now, it was simply not trusting Jesus. Every time a person looks to flesh or its mechanisms to complete them, it is the sin of idolatry. Only Christ is the redeemer of each event we encounter. It is not I with a little help from Jesus, nor a whole lot of Jesus with a bit of help from me. It sees Jesus as the Total and trusts in the Total He is.

Doubt is distrusting Jesus.

Self-improvement is a useless exercise. Christ has come to destroy the self that needs to improve. My soul attached to His Spirit is the Spirit of Christ Himself. He needs no improvement.
