We need to engage spiritual formation with intentionality because we are being formed unintentionally, whether we have chosen to be or not. Choosing intentional spiritual formation is at the heart of the call to repentance—it's not a one-time event, but an ongoing ethic.
Jesus' invitation to His first disciples is the same invitation given to us today: follow Him and become His apprentices. We are invited to be with Him, to become like Him, and to ultimately do what He did. The intentional choice is foundational for us to follow the Way because His way is the only pathway to the fullness of life.
