The book Echo of Jesus’ Prayer – in the Church challenges the modern Church to consider and respond to Jesus’ prayer for oneness in John 17:20-23.  In the February 2020 Blog, I asked if it were possible for Christians to believe the same.  Common belief is an important ingredient to oneness, but is that all that Jesus implied in his prayer?   He had asked the Father that through his indwelling of his followers, Then they’ll be mature in this one-ness (John 17:23, The Message).  What did he mean by associating maturity with oneness or unity?  What is Christian maturity?  What are the consequences of spiritual immaturity in believers in Jesus?  What role does Christian maturity play in the oneness that Jesus intends?  In the Blogs that follow, we will look into and endeavor to understand New Testament passages that address and answer these questions.
