Obedience

Came across this in God's word tonight, in summary of Samuel's life:

Heroic spiritual lives are built by stacking days of obedience on top of the other. Like a brick, each obedient act is small in itself, but in time the acts will pile up, and a huge wall of strong character will be built -- a great defense against temptation. We should strive for consistent obedience each day.

I'm trying to be more obedient......brick by brick. The wall I have built is still short and sometimes unstable, how is your building coming along?
