The word “Spirituality,” which has come into Protestant usage relatively recently, speaks to both the origins and the nature of the personal holiness. It originates with God, it is His initiative. We respond to His operation in us by the Holy Spirit.
As to the nature of spirituality, it is not legislated by laws or decrees. It is not mandated or manipulated by a Church, Christian culture, sub-cultures or family association. Biblical spirituality grows organically in the individual. While we have a common salvation and a shared Canon, biblical spirituality cannot be a cookie-cutter pattern. We must not simply mirror the life of another. Spirituality must be individually nuanced. Abraham was forbidden to go down to Egypt, while Jacob was commanded. Christ is the basis upon which spirituality is formed, the Holy Spirit is the agent, but God is the master to whom we answer individually (Romans 14:4).
