What we must realize is that while 'doing something' requires a risk. So does 'doing nothing.' The risk of action may be failure, but the risks of a failure to act can be stagnation, dissatisfaction,...and frustration...even loss to an evil enemy.
The story of the covered wagon crossing the plains toward the Golden West with a song:
The Coward never started;
The Weak died on the way;
Only the Strong came through!
That's the way it is in life. But strength does not refer only to physical strength. True strength flows from the strong spirit--a spirit made powerful by a close relationship with God. He gives us the will to succeed, the dreams that will not die, and the wisdom to turn any evil into a blessing.
Lean on God for direction, and keep leaning on Him for the wisdom and courage to finish what you begin!
This one thing I do, forgetting those things which are behind and reaching forth unto those things which are before.
