Things pertaining to the New Covenant can only be understood by those who have been circumcised in the heart, which equates to having been born again.
Baptism and being born again were already understood by the Jews, but the traditions had evidently blinded people to some additional spiritual nuances.
Being born again signifies a new spiritual beginning at the beginning of our conversion. We are not yet complete, though; we must go on to perfection.
The gestation or fetus analogy does not adequately depict the sanctification process in which there has to be volition, judgment, and conscious choice.
We must understand Jesus' words about being born again from a spiritual perspective. Interpreting His symbols physically obscures necessary truths.
God has singled each one of us out individually, calling us, gifting us with capabilities, and preparing us for eternal life as members of His family.
As the lives of the major biblical figures were predestined, so are our lives. God chooses, moves, and manages the lives of His servants.
The Abrahamic Covenant was made with one man, but it impacts all of mankind to the New Heaven and New Earth and beyond, involving billions of people.
God, as Creator, takes the initiative (as the potter over the clay) for the elect's salvation, enabling us to build the repertoire of habits called character.
The seven churches of Revelation 2-3 all existed simultaneously and the characteristics of five of them will apparently be extant at the return of Christ.
We must use Berean self-reflexiveness to become teachable, to search for hidden sins, to detect spiritual blindspots, and to admit when we are wrong.
Any syncretism with the world will lead to confusion. We must separate from the world in terms of its religious practices and its false gospels.
While the carnal mindset is hostile to everything in God's word, we have been provided a gift to enable us to overcome: the faith from being born of God.
Salvation is an ongoing work of God, obligating us to walk in the Spirit. If we do, we will be not captivated by the lusts of the flesh.
