True ambition is wanting to serve God.
Any other objectives (= ambitions) represent defiance of God.
Insecurity, fear, and worry also represent defiance of God.
They suggest not weakness but defiance.
Why?
Because they suggest the presence of objectives (= ambitions).
Insecurity = thinking I cannot fulfil my objectives.
Fear = thinking my objectives will not be fulfilled.
Worry = speculation about the non-fulfilment of my objectives.
The solution to these is not building up confidence.
The solution is destroying confidence in self and its ambitions.
Only in broken-heartedness will God have me.
