There is no problem in human life that apprenticeship to Jesus cannot solve.

The key, then, to loving God is to see Jesus, to hold him before the mind with as much fullness and clarity as possible. It is to adore him.

I would say the soul would be more than the engine. The soul would be like the computer system that coordinates everything, from the smog device to the fuel injection system to the brakes.

The real issue relating to exclusiveness is whether or not the Christian actually has a relationship with God, a presence of God, which non-Christians do not have. Apart from Christian spiritual formation as described here, I believe there is little value in claiming exclusiveness for the Christian way.

The core of the person is what he or she loves, and that is bound up with what they worship - that insight recalibrates the radar for cultural analysis. The rituals and practices that form our loves spill out well beyond the sanctuary. Many secular liturgies are trying to get us to love some other kingdom and some other gods.

Obedience to Christ is the easy way, take my yoke.

In accord with his original intent, the heavenly Father has in fact prepared an individualized kingdom for every person, from the outset of creation.
