I do emphasize that we cannot just get out of the Bible a definition of the soul.
The first act of love is always the giving of attention.
We are unceasing spiritual beings with an eternal destiny in God's great universe.
Make disciples. Surround them in the reality of the Trinity in a fellowship of disciples. Teach them to do everything Jesus says.
When we receive God's gift of life by relying on Christ, we find that God comes to act with us as we rely on him in our actions.
Spiritual formation cannot, in the nature of the case, be a 'private' thing, because it is a matter of whole-life transformation. You need to seek out others in your community who are pursuing the renovation of the heart.
